Question

An airplane pilot fell 340 m after jumping from an aircraft without his parachute opening. He landed in a snowbank, creating a crater 1.30 m deep, but survived with only minor injuries.

a) Assuming the pilot's mass was 94.0 kg and his terminal velocity was 45.0 m/s , estimate the work done by the snow in bringing him to rest. Model him as a particle.

b) Estimate the average force exerted on him by the snow to stop him.

c) Estimate the work done on him by air resistance as he fell.
