A bungee jumper with mass 60.0kg jumps from a high bridge. after reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 42.0s. He finally comes to a rest 30.0, below the level of the bridge.
a) estimate the spring stiffness constant of the bungee cord assuming simple harmonic motion (answer units: N/m)
b) estimate the unstretched length of the bungee cord assuming SHM (answer units: m)
