The airplane pilot falls 360 m after jumping from the aircraft devoid of his parachute opening. Luckily, he lands in a snow-bank, making a crater 1.1 m deep, and survives with just minor injuries. Supposing the pilot's mass is 82 kg and his terminal (that is, maximum) velocity while falling is 50 m/s, estimate the given.
(i) The work done by the snow in bringing him to rest.
(ii) The average force applied on him by the snow to stop him.
(iii) The work done on him by the air resistance as he fell.
