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. No air resistance. When does the kinetic energy of the ball have its maximum value? Answer 1. When the ball is caught because the speed is the lowest. 2. Not enough information 3. When the ball reaches the highest point. 4. The kinetic energy of the ball is always a constant. 5. When the ball is released because the speed is the highest.
