Problem

A woman with mass M standing on weight measuring platform repeatedly throws a ball with mass m up in the air and catches it. The ball is up in the air for half of each throw and catch cycle. What is the time averaged weight measured over many periods? Ignore air drag. a) (M+m)g(M + m)g b) (M+m)g2\frac{(M + m)g}{2} c) (M+2m)g(M + 2m)g d) (M−m)g(M - m)g e) Not enough information to find out.
