37PRACTICE PROBLEM
A bungee jumper with mass m falls from a platform that is at height L above a bridge. This setup results in a total fall distance of 2L meters before the bungee cord, which has an unstretched length of L and a spring constant k, starts to stretch. The cord is designed to ensure the jumper's safety by decelerating the fall. Determine the maximum extension y of the bungee cord using the jumper's mass m, the spring constant k, and the initial length of the cord L .
