An airplane pilot falls 360 m after jumping from the aircraft devoid of his parachute opening. Luckily, he lands in a snow-bank, creating a crater 1.4 m deep, and survives with just minor injuries. Supposing the mass of pilot is 75 kg and his terminal (maximum) velocity while falling is 50 m/s, estimate the given.
(i) The work done through the snow in bringing him to the rest.
(ii) The average force applied on him by the snow to stop him.
(iii) Work done on him by the air resistance as he fell.
