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

Answer 1

The potential energy is highest at it point of Max height...

Step-by-step explanation:

From the formula potential energy = mgh...

The greater the height, the greater the potential energy.

So considering the time interval it's at the time it takes the ball to reach the reversal point ( its Max height)

Answer 2

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

Step-by-step explanation:

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

`PE =mgh`

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