# Problem: An airplane pilot fell 370 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. Assuming the pilots mass was 88.0 kg and his terminal velocity was 46.0 m/s, estimate the:(a) work done by the snow in bringing him to rest(b) force exerted on him by the snow to stop him(c) work done on him by air resistance as he fell
