SPREADSHEET A rock climber is rappelling down the face of a cliff when his hold slips and he slides down over the rock face, supported only by the bungee cord he attached to the top of the cliff. The cliff face is in the form of a smooth quarter-cylinder with height (and radius) H _ 300m (Figure 7-58). Treat the bungee cord as a spring with force constant and unstressed length The climbers mass is (a) Using a spreadsheet program, make a graph of the rock climbers potential energy as a function of s, his distance from the top of the cliff measured along the curved surface. Use values of s between and (b) His fall began when he was a distance from the top of the cliff, and ended when he was a distance from the top. Determine how much energy is dissipated by friction between the time he initially slipped and the time when he came to a stop.
