What is the total momentum of the two balls before they collide?kg•m/sWhat is the total momentum of the two balls after they collide?kg•m/s A tennis ball (m = 0.2 kg) is thrown at a brick wall. It is traveling horizontally at 17 m/s just before hitting the wall and reboundsfrom the wall at 8 m/s, still traveling horizontally. The ball is in contact with the wall for 0.02 s. What is the magnitude of theaverage force of the wall on the ball?N
