Answer:
2. A baseball has a mass of 150 g. If the velocity of pitched ball has a magnitude of 40.5 m/s and the batted ball’s velocity is 54.5 m/s in the opposite direction, find the change in momentum of the ball.
Answer:
3. Two skaters collide and grab on to each other on frictionless ice. One of them, of mass 56.0 kg, is moving to the right at 1.95 m/s, while the other, of mass 55.0 kg, is moving to the left at 2.65 m/s. What is the velocity of these skaters just after they collide?
