Answer:
The bowling ball
Explanation:
The PE (gravitational potential energy) of an object is given by:
where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object above the ground
In this case, we are comparing the PE of a bowling ball and of a ping pong ball. The two balls are located at same height (h=5 m) and the gravitational acceleration is the same (g=9.8 m/s^2), so their PE depends only on their mass: since the bowling ball has a greater mass than the ping pong ball, the bowling ball will have a greater PE.
