Verified Answer :

Awhen it reaches the top of its flight

potential energy increases as the height of the object does, and the highest point of a ball's flight is when it reaches the top.

Answer:

A.when it reaches the top of its flight

Explanation:

The potential energy of an object is given by:

\(U=mgh\)

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth at which the object is located above the ground

Therefore, we see that the higher the object, the larger its potential energy: this means that the ball will have the greatest potential energy at the top of its trajectory.
