A 0.062-kg tennis ball, traveling at 20m/s, hits a wall, rebounds with the same speed in the opposite direction, and is hit again by another player, causing the ball to return to the wall at the same speed. The collision of the ball with the wall lasts 1.0 ms. The ball returns to the wall once every 0.60 s. Determine the magnitude of the average force exerted on the ball during a single collision. Determine the force that the ball exerts on the wall averaged over
