A 84.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 105 N/m, and the system's damping constant is 0.137 kg/s. How long does it take for the oscillation amplitude to decrease to 90.6 % of its initial value? time:   s What is the frequency of oscillation? frequency: Hz

    A 90 kg student jumps off a bridge with a 8-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 400 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?
