Jocko the clown, who has a mass of 60.0 kg and stands at rest on the ice, catches a 15.0kg ball that is thrown to him at 20.0 km/hr. Jocko catches the ball and slides across the ice after the "collision". With what speed does Jocko (and the ball) move across the ice after the collision?Organize your work and show a clear solution to the problem. Accompany your answer by appropriate units.
