A golf ball has been hit off of the tee at an angle of elevation of 30 degrees and an initial velocity of 160 ft/sec.
The golf ball follows a parabolic path, and it is modeled by a quadratic function
The maximum height of the golf ball is 99.47 feet
How to determine the maximum height of the ball?The given parameters are:
Angle of elevation = 30 degrees Initial velocity, u = 160 ft/secThe maximum height of the ball is calculated using:
[tex]H_{max} = \frac{u^2\sin^2(\theta)}{2g}[/tex]
Where:
g = 32.17 ft/sec^2
So, we have:
[tex]H_{max} = \frac{160^2 * \sin^2(30)}{2 * 32.17}[/tex]
Evaluate
[tex]H_{max} = 99.47[/tex]
Hence, the maximum height of the golf ball is 99.47 feet

Two objects having equal masses and velocities collide with each other and come to a rest. Is momentum conserved in this case?
Two objects having equal masses and velocities collide with each other and come to a rest. In this case, the momentum is conserved.
What is conservation of momentum?Momentum of a object is the force of speed of it in motion. Momentum of a moving body is the product of mass times velocity.
When the two objects collides, then the initial collision of the two body is equal to the final collision of two bodies by the law of conservation of momentum.
The two objects has equal masses and velocities. These objects collide with each other and come to a rest. In this case momentum is conserved due to the law of conservation of momentum.Thus, two objects having equal masses and velocities collide with each other and come to a rest.

After an annual checkup, you leave your physician’s office, where you weighed 683 n. you then get into an elevator that, conveniently, has a scale. find the magnitude and direction of the elevator’s acceleration if the scale reads (a) 725 n and (b) 595 n.
The magnitude and direction of the elevator’s acceleration for the scale readings are; 0.6033 m/s² upwards and -1.264 m/s² downwards
What is the magnitude of acceleration?A) We are given;
Weight of man; W = 683 N
Mass is gotten from;
m = W/g
where g is acceleration due to gravity = 9.81 m/s²
m = 683/9.81
m = 69.62 kg
Now, scale reading of lift is w = 725 N. Thus;
Apparent weight = 725 - 683
Apparent weight = 42 N which is is the force that acts on the body which generates the acceleration.
Thus, acceleration is;
a = 42/69.62
a = 0.6033 m/s² upwards
B) At scale reading of 595 N;
Apparent weight = 595 - 683 = -88 N
Acceleration;
a = -88/69.62

An account is opened with $7,595.96 with a rate of increase of 2% per year. after 1 year, the bank account contains $7,746.90. assuming no deposits or withdrawals are made, which equation can be used to find y, the amount of money in the account after x years? (round money values to the nearest penny.)
Answer:
It's C
Step-by-step explanation:
y = 7,595.96(1.02)x
the initial beginning value times .02 after adding 1 to it so you would get 1.02 instead since it's an increase raised by x which indicates how many years it was to reach the new value.
