Plans to do a bungee jump off a bridge. They will just tip over the edge of the bridge and fall i. E. They are essentially falling from rest. The bungee is an elastic cord. The stiffness of the elastic cord is k = 75 N/m. The bridge is 150 m above the surface of the river running under the bridge. Determine the maximum unstretched length of the elastic cord so that the student doesn’t get wet when they jump.
