*11. GO A student (m = 63 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of 0.040 s. The average force exerted on him by the ground is +18 000 N, where the upward direction is taken to be the positive direction. From what height did the student fall? Assume that the only force acting on him during the collision is that due to the ground.

A 2.4 kg ball strikes a wall with a velocity of7.1 m/s to the left. The ball bounces off witha velocity of 5.9 m/s to the right.If the ball is in contact with the wall for0.23 s, what is the constant force exerted onthe ball by the wall?Answer in units of N.
A 7.500 E+3-kg truck moving east at 10.3 m/s collides with a 2.500 E+3-kg car moving west at 35.0 m/s. The collision takes place over a time interval of 0.5 s. The car and the truck stick together after the collision. Find the force (in N) of the car on the truck during the collision. Call this force positive if it points to the east, and negative if it points to the west. (Could you give an explanation on how to transfer/ convert E +3)
