Amos Moses, a 120 kg shot-putter, is putting the 5 kg shot in a track meet. Just before he releases the shot, Amos is in the air (his feet are off the ground).  At this instant, the only force he exerts against the shot is a 700 N horizontal force directed forward. What is Amos’s horizontal acceleration at this instant?   What is Amos’s vertical acceleration at this instant?   What is the shot’s horizontal acceleration at this instant?
