A 75 kg man just before contact with the ground has a speed of 6.4 m/s.
(b.) When he bends his knees, he comes to a halt in 0.10 s. What is the average net force now?
(c.) During the landing, the force of the ground on the man points upward, while the force due to gravity points downward. The average net force acting on the man includes both of these forces. Taking into account the directions of the forces, what is the force of the ground on the man in parts (a) and (b).
The solution shows how to calculate the force acting on the man during landing onto the ground using impulse-momentum theorem.
