Answer:

The answer is below

Explanation:

a) The initial velocity (u) = 24 m/s

We can solve this problem using the formula:

v² = u² - 2gh

where v = final velocity, g= acceleration due to gravity = 9.8 m/s², h = height.

At maximum height, the final velocity = 0 m/s

v² = u² - 2gh

0² = 24² - 2(9.8)h

2(9.8)h = 24²

2(9.8)h = 576

19.6h = 576

h = 29.4 m

b) The time taken to reach the maximum height is given as:

v = u - gt

0 = 24 - 9.8t

9.8t = 24

t = 2.45 s

The total time needed for the apple to return to its original position = 2t = 2 * 2.45 = 4.9 s

Which of the following statements most accurately differentiates potential and kinetic energy? A. Any object that has no motion
Aleks [24]

Answer:

B. Any object that has motion has potential energy, wow any object not in motion light with the potential to do work and kinetic.

Explanation:

Potential Energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Kinetic Energy is energy which a body possesses by virtue of being in motion.

What are forces that two objects apply on each other
liq [111]
Answer: Whenever two objects are touching, they usually exert forces on each other. The force of gravity, on the other hand, is an example of a force that exists between objects without them having to be in contact. Objects with mass exert forces on each other via the force of gravity.

If the car's speed decreases at a constant rate from 77 mi/h to 50 mi/h in 3.0 s, what is the magnitude of its acceleration, ass
Lostsunrise [7]

The acceleration of the car,

a = \frac{v-u}{t}

Here, v is final velocity, u is initial velocity and t is time taken by the car.

Given u =77 \ mil/h ,v = 50 mi/h and t = 3.0 s = 3.0 \times \frac{1 \ h}{3600} = 8.3 \times 10^{-4} h

Therefore, from above equation

a =  \frac{50 \ mi/h -77 \ mi/h}{8.33 \times 10^{-4} h} = - \frac{27 \ mi/h }{8.33 \times 10^{-4} h} = - 3.2 \times 10^{4} \ mi/h^2.

Here, negative sign shows deceleration of a car.

Thus the the magnitude of car acceleration is 3.2 \times 10^{4} \ mi/h^2.

2. Use the diagram below to answer this question. As the ball moves from point A to C what is happening to the energy? Explain t
OLga [1]

Answer/Explanation:

The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.

A: most potential and least kinetic

B: losing potential gaining kinetic

C: losing more potential and gaining more kinetic

D: most kinetic and least potential

E: Gaining  potential and losing kinetic

F: Gaining more potential and losing more kinetic

G: more potential than kinetic but not the most potential
