A 68.0-kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. The spring constant of the bungee cord is 1.40 x 102 N/m, and the system's damping constant is 0.138 kg/s. How long does it take for the oscillation amplitude to decrease to 90.5% of its initial value? What is the frequency of oscillation?
