You and a friend are playing tennis. Earth is the object of reference.
part A: What is the magnitude of the momentum of the 0.057-kg tennis ball when it travels at a speed of 32 m/s?
part B: At what speed must your 0.32-kg tennis racket move to have the same magnitude momentum as the ball?
part C: If you run toward the ball at a speed of 4.4 m/s, and the ball is flying directly at you at a speed of 32 m/s, what is the magnitude of the total momentum of the system (you and the ball)? Assume your mass is 60 kg.
