A ball is thrown with enough speed straight up so taht it is in teh air for several seconds. (a) What is the velocity of the ball when it gets to its highest point? (b) What is the velocity 1s before it reaches its highest point? (c) What is the change in velocity during this 1s interval? (d) What is its velocity 1s after it reaches its highest point? (e) What is the change in velocity during this 1s interval? (f) What is the change in velocity during the 2s interval? (g) What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?(adsbygoogle = window.adsbygoogle || []).push({});

I am completely and utterly confused. Can someone please help me walk through this?
