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 0.0200 s. The average force exerted on him by the
ground is +18500. 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. is this a problem solved using a
kinematic equation?
