- A system consists of a 4 kg block moving with velocity 14, 13, 0 m/s and a 5 kg block moving with velocity m/s. (a) What is the momentum of this two-block system? Ptotal (36,77,0) kg. m/s = (b) Next, due to interactions between the two blocks, each of their velocities change, but the two-block system is nearly isolated from the surroundings. Now what is the momentum of the two-block system? Ptotal kg. m/s XA rubber ball with a mass of 0.3 kg is dropped onto a steel plate. The ball's velocity just before impact is 4.5 m/s and just after impact is 4.2 m/s. What is the change in the ball's momentum?
