Question

You have a summer job working for a company that arranges bungee jumps in which the jumpers step off a high platform with a bungee cord attached to their legs. The cords used in the jump are sorted by their unstretched length and elasticity. Your first task is to help the employees pick out cords by developing an equation for the unstretched length of a cord that is appropriate for a jump, given the mass of the jumper and the height of the jump. For the most exciting jump, the person should stop just short of the ground. To keep the jumper safe, the company doctor recommends that the maximum acceleration of the person during the jump be no larger than 2g. To test your equation, you consider a person that weighs 150lbs with a jump height of 120m.
