1. The problem statement, all variables and given/known data A juggler is able to handle four balls simultaneously. He takes 0.5 s to cycle each ball through his hands, throw the ball, and be ready to catch the next ball. (a) With what velocity must he throw each ball up? (b) What is the position of the other three balls when he has just caught one of the balls? (c) How high must he throw the balls if he is to juggle five balls? 2. Relevant equations Rotational kinematics eqns. Rotational kinetic energy etc. 3. The attempt at a solution I'm not really sure.. A point in the right direction would help..
