In one series of aircraft exercises, a pilot went down 370 m after ejecting from his jet plane and unfortunately, his parachute did not open. Luckily, he landed on a big bunch of haystacks, creating a crater 1.1 m deep, and very lucky enough, managed to survive getting only minor bruises. Assuming the pilot's mass was 88 kg and his speed at impact was a rough estimate of 44.5 m/s: Calculate (a) the work done by the haystack in bringing him to rest; (b) the average force exerted on him by haystacks to stop him; and (c) the work done on him by air resistance as he went down. Apply particle model for the pilot.
