Figure 6-4
-A ball of mass 1 kg is flying horizontally and hits the hand with velocity 1.5 m/s, producing rotation of the underarm around the joint. The place where the ball hits the hand is at a distance l = 0.4 m from the joint (see Fig. 6.4). The underarm and hand together have a mass of 1.77 kg. What is the speed of the arm and the ball after the catch, assuming that no muscles were fighting the rotation?
