A 58-g handball moving with a speed of 5.3 m/s strikes the wall at an angle of 35° with the normal, and then bounces off with the same speed at the same angle with the normal. It is in contact with the wall for 2.0 ms. What is the average force exerted by the ball on the wall?
During the collision with the ground, he comes to rest in a time of .101 s. The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction. Elucidate from what height did the student f..
