    "A 74.3 kg man steps out a window and falls (from rest) 1.01 m to a sidewalk. If the man falls with his knees and ankles locked, the only cushion for his fall is a 0.488 cm give in the pads of his feet. Calculate the average force exerted on him by the ground in this situation. This average force is sufficient to cause cartilage damage in the joints or to break bones."

    m = 74.3 kg
    h = 1.01 m
    cushion thickness = 0.488 cm = 0.00488 m
    h_eff = 1.01 - 0.00488 = 1.00512 m
    When his cushion toches the ground, the man will have maximum ...
