Question

An airplane pilot fell 370m after jumping out from an aircraft without his parachute opening. he landed in a very soft snow bank, creating crater 1.10m deep, but survived. The terminal velocity of the pilot just before the impact was 45m/s and his mass is 88kg.

A)from the difintion of work done by a force, determine the work done by the gravitational force from the inital point of impact to the pint where the pilot comes to complete stop.

B) Through the application of the work-enegery thm. find the work done by the soft snow in bringing the pilot to a complete stop.

C) determine the avg. force exterted on the piolot by the soft snow in bringing to a complete stop.

Explanation / Answer

a)work by gravity=mgh=88*9.8*370=319088 joules b)work done by snow=-work done by gravity=-319088 joules c)Force=m*a=88*(V^2/2*s)=88*45^2/2*1.1=81000Newton
