The velocity of the center of mass never changes a collision. The final velocity is equal to the initial velocity. 1. A 55 kg skater at rest on a frictionless rink throws a 3 kg ball, giving the ball a velocity of 8 m/s. What is the velocity of the center of mass? 2. A 55 kg skater is skating at 3 m/s to the right with a 3 kg ball in their hands. The skater throws a 3 kg ball, giving the ball a velocity of 8 m/s. What is the velocity of the center of mass?
