1. A 0.280 kg volleyball approaches a player horizontally with a speed of +15.0 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 22.0 m/s. a. What impulse is delivered to the ball by the player? b. If the player's fist is in contact with the ball for 0.060 s, find the magnitude of the average force exerted on the player's fist. c. What is the change in the kinetic energy of the ball?
