An airplane pilot fell 400 m after jumping without his parachute opening. He landed in a snowbank, creating a crater 2 m deep, but survived with only minor injuries. Assume that the pilot's mass was 50 kg and his terminal velocity was 65 m/s.
(a) Estimate the work done by the snow in bringing him to rest.
Is it just work done by gravity, which is mgh, h being 402 m?
(b) Estimate the average force exerted on him by the snow to stop him.
No idea...
(c) Estimate the work done on him by air resistance as he fell.
No clue...
