Question

A student bounces a tennis ball. She drops the ball, and then it bounces back up to her. When does the ball have zero kinetic energy?(1 point)ResponsesAs soon as she drops itAs soon as she drops itAt the very top of its bounceAt the very top of its bounceExactly when it hits the groundExactly when it hits the groundJust after it hits the ground

Answer 1

The ball has zero kinetic energy at the very top of its bounce. At this point, the ball comes to a brief stop before starting to fall again, meaning its velocity is zero and therefore its kinetic energy is also zero. So the correct response is:

**At the very top of its bounce.**
