A bungee jumper steps off a high bridge while connected to it by a long elastic rope that obeys Hooke’s law. The jumper’s gravitational potential energy is taken relative to the lowest point reached by the jumper. Which graph shows how the jumper’s gravitational potential energy, and the elastic potential energy in the rope, vary with the vertical distance fallen from the top of the bridge?
