You throw a ball straight up. Just after it leaves your hand, the ball is traveling at 15.0 m/s. What is the speed of the ball at the moment the ball reaches maximum height? Submit AnswerTries 0/10 What is the acceleration of the ball (both magnitude and direction) at the moment the ball is at maximum height? Downward No direction O Upward Submit AnswerTries 0/10 Post Discussion Send FeedbackExplanation / Answer
Ans
1) When the ball is at maximum height the ball stops momemtarily before it starts to come down. Therefore at maximum height the speed of the ball is zero.
2) Once the ball leaves your hand, it has acceleration with magnitude equal to g and it's pointing downward (i.e how ball speed at maximum height reaches zero from 15.0 m/s).
