An airplane pilot fell 365 m afterjumping from an aircraft without his parachute opening. He landedin a snowbank, creating a crater 1.3 mdeep, but survived with only minor injuries. Assuming the pilot'smass was 75 kg and his terminal velocitywas 50 m/s, estimate the following.
(a) the work done by the snow in bringing him to the rest.
(b) the average force exerted on him by the snow to stophim.
(c) the work done on him by the air resistance as he fell.
