A 90 kg student jumps off a bridge with a 11-mm-long bungee cord tied to his feet. The mass less bungee cord has a spring constant of 390 N/m. You can assume that the bungee cord exerts no force until it begins to stretch. How far below the bridge is the student's lowest point? How far below the bridge is the student's resting position after the oscillations have been fully damped?
