Question

A ball is tossed in the air and released. It moves up, reverses direction, falls back down again, and is caught at the same height it was released.

a. Considering the interval after the ball is released and before it is caught, when does the gravitational potential energy of the ball have its maximum value? minimum value? explain.

b. When does the kinetic energy of the ball have its maximum value?minimum value? explain

c. What can you say about the mechanical eenergy of theball. What can you say about the value at the locationsdescribed in your answers to (a) and (b)

Answer:The potential energy has a maximum when the ball is a time that is half of the time for total travel

Explanation:

Generally potential energy is a the varies directly with the height according to this formula

and the ball attains a maximum height when the time is equal to half of the total time taken to travel

Explanation:
