A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 50.4 m/s and returns the shot with the ball traveling horizontally at 39.6 m/s in the opposite direction. (Take the direction of the ball's final velocity (toward the net) to be the +x-direction.) (a) What is the impulse delivered to the ball by the racket? magnitude N · s direction +x Correct: Your answer is correct. (b) What work does the racket do on the ball? (Indicate the direction with the sign of your answer.) J

A soccer ball of mass 0.30 kg is rolling with velocity 0, 0, 3.0 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.6 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.28 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...
