A person hits a tennis ball with a mass of 0.058 kg against a wall. The average component of the ball's velocity perpendicular to the wall is 11 m/s, and the ball hits the wall every 2.1 s on average, rebounding with the opposite perpendicular velocity component. If the part of the wall the person hits has an area of 3.0 m what is the average pressure on that area? 0.30 Pa 0.10 Pa 0.20 Pa 0.40 Pa
