The expression for the SHM is x = 0.12 * cos(πt). We can start by using the general equation for SHM: x = A * cos(ωt + φ). The particle passes the origin (O) for the first time at t = 0.5 s. we can start by using the general equation for SHM: x = A * cos(ωt + φ).

To find the expression for the Simple Harmonic Motion (SHM) of the particle, we can start by using the general equation for SHM:

x = A * cos(ωt + φ)

Where:

x is the displacement from the equilibrium position,

A is the amplitude of the motion,

ω is the angular frequency, given by ω = 2π/T (T is the period),

t is the time, and

φ is the phase constant.

Given that A = 0.12 m and T = 2 s, we can find the angular frequency:

ω = 2π / T

= 2π / 2

= π rad/s

The expression for the SHM becomes:

x = 0.12 * cos(πt + φ)

To find the phase constant φ, we can use the initial conditions given. When t = 0, x₀ = 0.06 m, and v > 0.

Substituting these values into the equation:

0.06 = 0.12 * cos(π * 0 + φ)

0.06 = 0.12 * cos(φ)

Since the particle starts from the equilibrium position, we know that cos(φ) = 1. Therefore:

0.06 = 0.12 * 1

φ = 0

So, the expression for the SHM is:

x = 0.12 * cos(πt)

Now let's move on to the next parts of the question:

(2) At t = T/4, we have:

t = T/4 = (2/4) = 0.5 s

To find the velocity v at this time, we can take the derivative of the displacement equation:

v = dx/dt = -0.12 * π * sin(πt)

Substituting t = 0.5 into this equation:

v = -0.12 * π * sin(π * 0.5)

v = -0.12 * π * sin(π/2)

v = -0.12 * π * 1

v = -0.12π m/s

So, at t = T/4, v = -0.12π m/s.

To find the acceleration a at t = T/4, we can take the second derivative of the displacement equation:

a = d²x/dt² = -0.12 * π² * cos(πt)

Substituting t = 0.5 into this equation:

a = -0.12 * π² * cos(π * 0.5)

a = -0.12 * π² * cos(π/2)

a = -0.12 * π² * 0

a = 0

So, at t = T/4, a = 0 m/s².

(3) To find the time when the particle passes the origin (O) for the first time, we need to find the time when x = 0.

0 = 0.12 * cos(πt)

Since the cosine function is zero at π/2, π, 3π/2, etc., we can set the argument of the cosine function equal to π/2:

πt = π/2

Solving for t:

t = (π/2) / π

t = 0.5 s

Therefore, the particle passes the origin (O) for the first time at t = 0.5 s.

(a) The magnitude of the velocity 1.8 s before reaching the maximum height is approximately 8.14 m/s. (b) The magnitude of the velocity 1.8 s after reaching the maximum height is approximately

To calculate the magnitude of the velocity of the projectile 1.8 s before it reaches its maximum height, we can use the principle of conservation of energy. At its maximum height, all the initial kinetic energy is converted to potential energy.

(a) The magnitude of the velocity at maximum height is 11 m/s, we can calculate the velocity 1.8 s before using the equation for conservation of energy:

Potential energy at maximum height = Kinetic energy 1.8 s before maximum height

mgh = (1/2)mv^2

where m is the mass of the projectile, g is the acceleration due to gravity, h is the maximum height, and v is the velocity.

Since the mass and acceleration due to gravity are constant, we can write:

h = (1/2)v^2 / g

Substituting the given values, we have:

h = (1/2)(11^2) / 9.8

h ≈ 6.04 m

Now, using the equations of motion for vertical motion:

v = u + gt

where u is the initial velocity (which is the velocity at maximum height) and g is the acceleration due to gravity.

Substituting the values:

v = 11 + (-9.8)(1.8)

v ≈ -8.14 m/s (negative sign indicates the velocity is in the opposite direction)

Therefore, the magnitude of the velocity 1.8 s before reaching the maximum height is approximately 8.14 m/s.

(b) To calculate the magnitude of the velocity 1.8 s after reaching the maximum height, we can use the same approach. The equations of motion remain the same, but the initial velocity will now be the velocity at the maximum height.

v = u + gt

v = 11 + (9.8)(1.8)

v ≈ 27.24 m/s

Therefore, the magnitude of the velocity 1.8 s after reaching the maximum height is approximately 27.24 m/s.

(c) and (d) To determine the x and y coordinates 1.8 s before reaching the maximum height, we can use the equations of motion:

x = uxt

y = uyt + (1/2)gt^2

Since the projectile is at its maximum height, the y-coordinate will be the maximum height (h) and the y-velocity (uy) will be zero. Substituting the values, we have:

x = (11)(1.8) = 19.8 m

y = 6.04 m

Therefore, the x-coordinate 1.8 s before reaching the maximum height is approximately 19.8 m and the y-coordinate is approximately 6.04 m.

(e) and (f) To calculate the x and y coordinates 1.8 s after reaching the maximum height, we can use the same equations:

x = uxt

y = uyt + (1/2)gt^2

Since the projectile is at its maximum height, the y-coordinate will remain the same (h) and the y-velocity (uy) will still be zero. Substituting the values, we have:

x = (11)(1.8) = 19.8 m

y = 6.04 m

Therefore, the x-coordinate 1.8 s after reaching the maximum height is approximately 19.8 m and the y-coordinate remains approximately 6.04 m.

The average force exerted by the ball on the bat during their interaction is approximately [tex]\( 5.08 \times 10^3 \, \text{N} \)[/tex] in the upward direction.

To find the average vector force exerted by the ball on the bat, we can use Newton's second law of motion, which states that the force exerted on an object is equal to the rate of change of its momentum.

The momentum of an object can be calculated as the product of its mass and velocity:

[tex]\[ \text{Momentum} = \text{Mass} \times \text{Velocity} \][/tex]

Let's first calculate the initial momentum of the ball in the x-direction and the final momentum in the y-direction.

Given:

Mass of the ball, [tex]\( m = 145 \, \text{g} \\= 0.145 \, \text{kg} \)[/tex]

Initial velocity of the ball in the x-direction, [tex]\( v_{x_i} = 46.0 \, \text{m/s} \)[/tex]

Final velocity of the ball in the y-direction, [tex]\( v_{y_f} = 56.0 \, \text{m/s} \)[/tex]

Contact time, [tex]\( \Delta t = 1.60 \times 10^{-3} \, \text{s} \)[/tex]

The change in momentum in the x-direction can be calculated as:

[tex]\[ \Delta p_x = m \cdot (v_{x_f} - v_{x_i}) \][/tex]

Since the velocity does not change in the x-direction, [tex]\( v_{x_f} = v_{x_i} = 46.0 \, \text{m/s} \)[/tex], the change in momentum in the x-direction is zero.

The change in momentum in the y-direction can be calculated as:

[tex]\[ \Delta p_y = m \cdot (v_{y_f} - v_{y_i}) \][/tex]

Since the initial velocity in the y-direction, \( v_{y_i} \), is zero, the change in momentum in the y-direction is equal to the final momentum in the y-direction:

[tex]\[ \Delta p_y = p_{y_f} = m \cdot v_{y_f} \][/tex]

The average force exerted by the ball on the bat in the y-direction can be calculated as:

[tex]\[ \text{Average Force} = \frac{\Delta p_y}{\Delta t} \][/tex]

Substituting the given values:

[tex]\[ \text{Average Force} = \frac{m \cdot v_{y_f}}{\Delta t} \][/tex]

Calculating the value:

[tex]\[ \text{Average Force} = \frac{(0.145 \, \text{kg}) \cdot (56.0 \, \text{m/s})}{1.60 \times 10^{-3} \, \text{s}} \][/tex]

Given data are: Initial velocity of the baseball (u) = 46.0 m/s

Final velocity of the baseball (v) = 56.0 m/s

Mass of the baseball (m) = 145 g = 0.145 kg

Time taken by the ball to be hit by the bat (t) = 1.60 ms = 1.60 × 10⁻³ s

Final velocity of the baseball is in the +y-direction. Therefore, the vertical component of the ball's velocity, v_y = 56.0 m/s.

Now, horizontal component of the ball's velocity, v_x = u = 46.0 m/s

Magnitude of the velocity vector is given as:v = √(v_x² + v_y²) = √(46.0² + 56.0²) = 72.2 m/s

Change in momentum of the baseball, Δp = m(v_f - v_i)

Let's calculate the change in momentum:Δp = 0.145 × (56.0 - 46.0)Δp = 1.45 Ns

During the collision, the ball is in contact with the bat for a time interval t. Therefore, we can calculate the average force exerted on the ball by the bat as follows: Average force (F) = Δp/t

b) The current amplitude at the resonant frequency is approximately 0.0159 A.

c) The current amplitude at an angular frequency of 403 rad/s is approximately 0.00762 A.

d) At the frequency of 403 rad/s, the source voltage will lag the current.

A series circuit is an electrical circuit configuration in which the components (such as resistors, inductors, capacitors, etc.) are connected in a sequential manner, such that the same current flows through each component. In a series circuit, the components have a single pathway for the flow of electric current.

To answer the given questions, we will use the formulas and concepts from AC circuit analysis. Let's solve each part step by step:

a) To find the frequency at which the current in the circuit will be greatest, we can calculate the resonant frequency using the formula:

Resonant frequency:

[tex](f_{res}) = 1 / (2\pi \sqrt(LC))[/tex]

Substituting the values into the formula:

[tex]f_{res} = 1 / (2\pi \sqrt(0.410 H * 5.01 * 10^{-6}F))\\f_{res} = 1.03 kHz[/tex]

Therefore, the current in the circuit will be greatest at a frequency of approximately 1.03 kHz.

b) To calculate the current amplitude at the resonant frequency, we can use the formula:

Current amplitude:

[tex](I) = V / Z[/tex]

Where:

V = Amplitude of the AC source voltage (given as 3.07 V)

Z = Impedance of the series circuit

The impedance of a series RLC circuit is given by:

[tex]Z = \sqrt(R^2 + (\omega L - 1 / \omega C)^2)[/tex]

Converting the frequency to angular frequency:

[tex]\omega = 2\pi f = 2\pi * 1.03 * 10^3 rad/s[/tex]

Substituting the values into the impedance formula:

[tex]Z = \sqrt((191 \Omega)^2 + ((2\pi * 1.03 *10^3 rad/s) * 0.410 H - 1 / (2\pi * 1.03 * 10^3 rad/s * 5.01 * 10^{-6} F))^2)[/tex]

Calculating the impedance (Z):

[tex]Z = 193 \Omega[/tex]

Now, substitute the values into the current amplitude formula:

[tex]I = 3.07 V / 193 \Omega\\I = 0.0159 A[/tex]

Therefore, the current amplitude at the resonant frequency is approximately 0.0159 A.

c) To find the current amplitude at an angular frequency of 403 rad/s, we can use the same current amplitude formula as in part b. Substituting the given angular frequency (ω = 403 rad/s) and calculating the impedance (Z) using the same impedance formula:

[tex]Z = \sqrt((191 \Omega)^2 + ((403 rad/s) * 0.410 H - 1 / (403 rad/s * 5.01 * 10^{-6} F))^2)[/tex]

Calculating the impedance (Z):

[tex]Z = 403 \Omega[/tex]

Now, substitute the values into the current amplitude formula:

[tex]I = 3.07 V / 403 \Omega\\I = 0.00762 A[/tex]

Therefore, the current amplitude at an angular frequency of 403 rad/s is approximately 0.00762 A.

d) To determine if the source voltage leads or lags the current at a frequency of 403 rad/s, we need to compare the phase relationship between the voltage and the current.

In a series RL circuit like this, the voltage leads the current when the inductive reactance (ωL) is greater than the capacitive reactance (1 / ωC). Conversely, the voltage lags the current when the capacitive reactance is greater.

Let's calculate the values:

Inductive reactance:

[tex](XL) = \omega L = (403 rad/s) * (0.410 H) = 165.23 \Omega[/tex]

Capacitive reactance:

[tex](XC) = 1 / (\omega C) = 1 / ((403 rad/s) * (5.01* 10^{-6} F)) = 498.06 \Omega[/tex]

Since XC > XL, the capacitive reactance is greater, indicating that the source voltage lags the current.

Therefore, at a frequency of 403 rad/s, the source voltage will lag the current.

The ratio of the orbital radii of the two particles is 16, i.e., R1 / R2 = 16.

In a magnetic field, the radius of the circular orbit for a charged particle is determined by the equation:

R = (mv) / (|q|B),

where R is the radius of the orbit, m is the mass of the particle, v is its velocity, |q| is the magnitude of its charge, and B is the magnetic field strength.

Given that both particles are moving with the same velocity and in the same magnetic field, their velocities (v) and magnetic field strengths (B) are the same.

Let's denote the mass of particle 2 as m2. Since the mass of particle 1 is 8 times the mass of particle 2, we can write the mass of particle 1 as 8m2.

The charge of particle 1 is half the charge of particle 2, so we can write the charge of particle 1 as 0.5|q|.

Now, let's compare the ratios of their orbital radii:

R1 / R2 = [([tex]m^1[/tex]* v) / (|q1| * B)] / [([tex]m^2[/tex] * v) / (|q2| * B)],

Substituting the values we obtained:

R1 / R2 = [([tex]8m^{2}[/tex] * v) / (0.5|q| * B)] / [([tex]m^2[/tex] * v) / (|q| * B)],

Simplifying the expression:

R1 / R2 = [(8 * v) / (0.5)] / 1,

R1 / R2 = 16.

Therefore, the ratio of the orbital radii of the two particles is 16, i.e., R1 / R2 = 16.

Dielectric materials, such as paper and glass, affect the capacitance of a capacitor by their dielectric constant. The dielectric constant is a measure of how effectively a material can store electrical energy in an electric field. It determines the extent to which the electric field is reduced inside the dielectric material.

The glass sheet will not have the same dependence on area and plate separation as the paper dielectric. The effect of swapping the paper for glass is that the glass will have a different dielectric constant (also known as relative permittivity) compared to paper.

In general, the higher the dielectric constant of a material, the higher the total capacitance of the capacitor. This is because a higher dielectric constant indicates that the material has a greater ability to store electrical energy, resulting in a larger capacitance.

Glass typically has a higher dielectric constant compared to paper. For example, the dielectric constant of paper is around 3-4, while the dielectric constant of glass is typically around 7-10. Therefore, the glass dielectric would have a higher dielectric constant and hence a higher total capacitance compared to the paper dielectric, assuming all other factors (such as plate area and separation) remain constant.

In summary, swapping the paper for glass as the dielectric material in the capacitor would increase the capacitance of the capacitor due to the higher dielectric constant of glass.

Incandescent lamps are lamps that produce light by heating a filament until it glows. They are relatively inexpensive, have a warm color temperature, and can be dimmed easily.

However, they are highly inefficient, converting only about 5% of the energy they consume into visible light.

The remaining 95% of the energy is released as heat, making them hot to the touch and wasteful to operate.

Fluorescent lamps, on the other hand, produce light by passing an electric current through a gas that contains mercury vapor.

The mercury vapor emits ultraviolet light, which is absorbed by a phosphorescent coating on the inside of the lamp, causing it to glow.

Fluorescent lamps are much more efficient than incandescent lamps, converting about 25% of the energy they consume into visible light.

The transmitted beam's intensity is reduced by a fraction of 93.75% in this scenario.

In this scenario, an unpolarized beam of light passes through a stack of four ideal polarizing filters. Each filter has its transmission axis at a 30.0⁰ angle relative to the preceding filter. We need to find the fraction by which the transmitted beam's intensity is reduced.

When an unpolarized light beam passes through a polarizing filter, it becomes linearly polarized along the transmission axis of the filter. Subsequent filters can only transmit light that is polarized in the same direction as their transmission axis.

In this case, the first filter will polarize the light in a specific direction, let's say vertically. As the light passes through the subsequent filters, which are at 30.0⁰ angles, the intensity of the transmitted beam will decrease.

Each filter will transmit 50% of the light that reaches it. So, after passing through the first filter, the intensity is reduced by 50%. The second filter will further reduce the intensity by 50% of the remaining light, resulting in a total reduction of 75%.

The third filter will reduce the intensity by an additional 50% of the remaining light, resulting in a total reduction of 87.5%. Finally, the fourth filter will reduce the intensity by another 50% of the remaining light, resulting in a total reduction of 93.75%.

Therefore, the transmitted beam's intensity is reduced by a fraction of 93.75% in this scenario.

Note: The specific angles and number of filters in the stack may vary, but the principle of each filter transmitting 50% of the polarized light and reducing the intensity remains the same.

Young's double-slit interference apparatus is a famous experiment that demonstrates the wave nature of light. When light passes through two parallel slits, it produces an interference pattern on a screen behind it. The pattern consists of alternating bright and dark fringes. The answer to this question is option C) widens.

The interference pattern generated by the two slits is a function of the distance between them. The distance between the slits affects the path length difference of the light waves that pass through each slit. When the distance between the slits is reduced, the distance traveled by each beam of light through the slits is also reduced.

The density of the object is  1000 kg/m³ when weight of the object is 5N and  the reading on the balance is 3.5.

Given Weight of the object (W) = 5 N

Reading on the spring balance (S) = 3.5 N

Since the reading on the spring balance is the apparent weight of the object in water, it is equal to the difference between the weight of the object in air and the buoyant force acting on it.

Apparent weight of the object in water (W_apparent) = W - Buoyant force

Buoyant force (B) = Weight of displaced water

To find the density of the object, we need to determine the volume of water displaced by the object.

Since the weight of the object is equal to the weight of the displaced water, we can equate the weights:

W = Weight of displaced water

5 N = Weight of displaced water

The volume of water displaced by the object is equal to the volume of the object.

Now, let's calculate the density of the object:

Density (ρ) = Mass (m) / Volume (V)

Since the weight (W) is equal to the product of mass (m) and acceleration due to gravity (g), we have:

W = mg

Rearranging the formula, we can find the mass:

m = W / g

Given that g is approximately 9.8 m/s², substituting the values:

m = 5 N / 9.8 m/s²

= 0.51 kg

Since the volume of water displaced by the object is equal to its volume, we can calculate the volume using the formula:

Volume (V) = Mass (m) / Density (ρ)

Substituting the known values:

Volume (V) = 0.51 kg / ρ

Since the weight of water displaced is equal to the weight of the object:

Weight of displaced water = 5 N

Using the formula for the weight of water:

Weight of displaced water = ρ_water × V × g

Where ρ_water is the density of water and g is the acceleration due to gravity.

Substituting the known values:

5 N = (1000 kg/m³) × V × 9.8 m/s²

Simplifying the equation:

V = 5 N / ((1000 kg/m³) × 9.8 m/s²)

= 0.00051 m³

Now, we can calculate the density of the object:

Density (ρ) = Mass (m) / Volume (V)

ρ = 0.51 kg / 0.00051 m³

= 1000 kg/m³

Therefore, the density of the object is approximately 1000 kg/m³.

The magnetic flux through a coil containing 10 loops changes from 20Wb to-20Wb in 0.038.Then the induced voltage is 1052.63 V.

When the magnetic flux through a coil changes, it induces an electromotive force (EMF) or voltage. According to Faraday's law of electromagnetic induction, the magnitude of the induced voltage is directly proportional to the rate of change of magnetic flux. The formula to calculate the induced voltage is:

e = -N * (ΔΦ / Δt)

Where:

e is the induced voltage,

N is the number of loops in the coil,

ΔΦ is the change in magnetic flux, and

Δt is the time taken for the change in magnetic flux.

In this case, the coil contains 10 loops, and the magnetic flux changes from 20 Wb to -20 Wb. The change in magnetic flux (ΔΦ) is equal to the final flux minus the initial flux:

ΔΦ = (-20 Wb) - (20 Wb) = -40 Wb

The time taken for this change in magnetic flux (Δt) is given as 0.038 seconds.

Substituting these values into the formula, we get:

e = -10 * (-40 Wb / 0.038 s)

e = 1052.63 V

Therefore, the induced voltage is 1052.63 V.

The magnetic field does not directly affect the velocity of the aluminum. When a piece of aluminum is dropped vertically downward between the poles of an electromagnet, the force of gravity is primarily responsible for its motion.

The magnetic field generated by the electromagnet exerts a force on the aluminum, but this force acts perpendicular to the direction of motion.

As a result, the magnetic force does not change the speed of the aluminum. However, it does cause the aluminum to experience a sideways deflection due to the interaction between the magnetic field and the induced currents in the aluminum. This phenomenon is known as magnetic induction or the Eddy current effect.

The deflection caused by the magnetic field depends on factors such as the strength of the magnetic field, the mass and shape of the aluminum, and the speed at which it is falling. The higher the strength of the magnetic field, the greater the deflection. Similarly, the larger the mass or shape of the aluminum, the smaller the deflection.

In summary, the magnetic field generated by the electromagnet does not directly affect the velocity of the aluminum, but it does cause a sideways deflection known as the Eddy current effect.

The correct answer is option (a). Based on the length of the external canal of the human ear, which is approximately 3 cm, humans are especially sensitive to sound with a wavelength of about 10 cm.

The speed of sound in air is approximately 340 m/s. The relationship between the speed of sound, frequency, and wavelength is given by the equation:

v = f * λ,

where v is the speed of sound, f is the frequency, and λ is the wavelength.

The radius of Satellite Rock B's orbit (RB) is approximately 522.47 km.

To determine the radius of Satellite Rock B's orbit (RB), we can use Kepler's Third Law of Planetary Motion, which relates the orbital period and orbital radius of celestial bodies. Kepler's Third Law states that the square of the period (T) of an object in an orbit is proportional to the cube of its orbital radius (R).

Mathematically, it can be expressed as: T² ∝ R³

Given that Satellite Rock A has an orbital radius of R₁ = 280.0 km and a period of TA, we can write the following equation: TA² = R₁³

Now, let's consider Satellite Rock B. We are given that it takes Rock B a time TB = 3.78TA to orbit the asteroid once. Using the same equation, we can write: TB² = RB³

Since we want to find RB, we can rearrange the equation:

RB = (TB²)^(1/3)

Substituting the value of TB = 3.78TA, we get:

RB = (3.78TA²)^(1/3)

Since we know that TA² = R₁³, we can substitute this into the equation:RB = (3.78 * R₁³)^(1/3)

Now we can calculate the value of RB using the given radius of Satellite Rock A: RB = (3.78 * (280.0 km)³)^(1/3)

(a.)The speed of the probe as seen from the earth is approximately 0.970c. (b.) The length of the ship as measured by the ship's crew is approximately 6.15 m.

a. To calculate the speed of the probe as seen from the earth, we need to use the relativistic velocity addition formula:

v' = (v + u) / (1 + (vu/c^2)),

where v' is the velocity of the probe as seen from the earth, v is the velocity of the ship (relative to the earth), u is the velocity of the probe (relative to the ship), and c is the speed of light.

v = 0.850c (speed of the ship relative to the earth),

u = 0.780c (speed of the probe relative to the ship).

Substituting the values into the formula:

v' = (0.850c + 0.780c) / (1 + (0.850c)(0.780c)/(c^2))

= (1.63c) / (1 + 0.663)

≈ 0.970c.

Therefore, the speed of the probe as seen from the earth is approximately 0.970c. Since the speed is greater than the speed of light, it implies that the probe is moving away from the earth (as viewed from the earth).

b. The length of the ship as measured by the ship's crew can be calculated using the relativistic length contraction formula:

L' = L * √(1 - (v^2/c^2)),

where L' is the length of the ship as measured by the crew, L is the length of the ship as measured by an observer at rest (in this case, the earth), v is the velocity of the ship (relative to the earth), and c is the speed of light.

L = 4.50 m (length of the ship as measured from the earth),

v = 0.850c (speed of the ship relative to the earth).

Substituting the values into the formula:

L' = 4.50 m * √(1 - (0.850c)^2/c^2)

= 4.50 m * √(1 - 0.7225)

= 4.50 m * √(0.2775)

≈ 6.15 m.

Therefore, the length of the ship as measured by the ship's crew is approximately 6.15 m.

Given Data:Mass of object, m1 = 200 g

Stretched distance of spring, x = 50 cm= 0.5 m

New Mass of object, m2 = 400 g

The potential energy of the spring is given as:

Potential Energy of spring = (1/2)k(x^2)

where k is the spring constantLet k be the spring constant.

From Hooke's law of elasticity:

F = -kx

The force exerted by the spring is proportional to the distance by which it is stretched.

The negative sign indicates that the force is in the opposite direction to the force causing the deformation.

The proportionality constant is called the spring constant k, which is expressed in newton per meter or

N/m.k = - F / x

The force exerted on the spring can be calculated using:

Force, F = mass × acceleration

Using F = ma to get the value of acceleration, a:

a = F / ma = F / m

So, F = ma

Putting the value of F in k = - F / x:k = - ma / x

Let's find the spring constant k:

When a mass of 200 g is attached to the spring, the force exerted by the spring will be:

F = ma= 0.2 kg × 9.8 m/s²= 1.96 N

From Hooke's law of elasticity:F = -kx-1.96 = - k × 0.5-1.96 / 0.5 = - k-3.92 = - k

The spring constant k is 3.92 N/m.

Now let's find the potential energy of the spring when a mass of 400 g is attached to it.

Using the formula of potential energy:

Potential Energy of spring = (1/2)k(x^2)

Put the given values in the above formula:

Potential Energy of spring = (1/2)(3.92 N/m) × (0.5 m)²

Potential Energy of spring = (1/2)(3.92) × (0.25)

To solve this problem, we can use the principles of conservation of energy and Hooke's Law. The initial kinetic energy of the block is given by 1/2 * m * v^2, where m is the mass of the block and v is its initial velocity. The potential energy stored in the compressed spring can be calculated using the formula 1/2 * k * x^2, where k is the spring constant and x is the compression of the spring.

Since the initial kinetic energy of the block is converted into potential energy stored in the spring when the block compresses it, we can set up an equation equating the two energies: 1/2 * m * v^2 = 1/2 * k * x^2. Rearranging this equation, we find x, the compression of the spring.

By substituting the given values into the equation, we can calculate the distance the block compresses the spring.
