Three identical balls with mass m are thrown from the edge of a cliff with height h. The balls are in free fall, and their trajectories are shown. Which ball has the greatest gravitational potential energy when it reaches the peak of its trajectory? If there is more than one, you must select all of them. A B C O Ball A O Ball B Ball C O All three will have the same gravitational potential energy at the peak of their trajectory since they were thrown from the same initial height There's no way to tell without knowing the initial speeds of the balls
