Question

If you drop a 2.5kg ball that initially has 32J of potential energy, how much potential energy will it have before it hits the ground? Round your answer to the nearest whole and include the appropriate unit

Answer 1

Given:

The mass of the ball is 2.5 kg

The initial potential energy is 32 J.

To find the potential energy before it hits the ground.

Explanation:

The potential energy can be calculated as

$\begin{gathered} P.E.\text{ =mgh} \\ =\text{ 2.5}\times9.8\times0 \\ =\text{ 0 J} \end{gathered}$
