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) Responses As soon as she drops it As soon as she drops it Just after it hits the ground Just after it hits the ground Exactly when it hits the ground Exactly when it hits the ground At the very top of its bounce
I apologize for the confusion. The ball has zero kinetic energy at the very top of its bounce. At this point, the ball is momentarily at rest before it starts moving downwards again due to gravity.

Thank you for confirming! I'm glad I could provide the correct answer. If you have any more questions, feel free to ask.

My apologies for the confusion in my previous response. The ball actually has zero kinetic energy at the very top of its bounce. At that moment, it comes to a brief halt before reversing its direction and moving back downwards.
