Im really stuck with this question, hoping someone could give me a hand
A bungee rope of unstretched length 50M is designed to allow a 70Kg man to come to rest 85m below the platform from which he jumps.
Calculate the energy stored in the rope when the man has come to rest. Ignore the weight of the rope.
(Gravitational field strength 9.8)
Calculate the gravitational potential energy lost by the man when he comes to rest.
Am i right to do
70 x 9.8 = 686N
Work Done = Force x Displacement
=24.1Kj?
Im not sure if I am using the correct formula, and I am totally stuck on the 2nd part
