A student of mass 63 kg falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest at a time of 0.04 seconds. The average force exerted on him by the ground is 18,000 N, where the upward direction is taken to be a positive direction. From what height did the student fall? Assume that the only force acting on him during the collision is only due to the ground
