Kaitlyn, whose mass is 60kg, is standing on a roof. What is her weight? She jumps off the roof, what is her acceleration? How long does it take her to fall to the ground if the roof is 8m tall? How fast is she going when she gently hits the ground? If impact lasts 1.2s (stunt person air bag), how much force does she feel? If the impact lasts 0.02s (concrete), how much force does she feel?

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
