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.

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

on him by air resistance as he went down. Apply particle model for the pilot.
