Q. A paratrooper pilot fell 360 m after jumping without his parachute opening. He landed in a snow bank, creating a crater 1.50 m deep, but survived with only minor injuries. Assume the pilot's mass was 80 kg and his terminal velocity was 50 m/s.
(a) Estimate the work done by the snow in bringing him to the rest.
(b) Approximate the average force exerted on him by snow to stop him.
(c) Estimate the work done on him by air resistance as he fell.
