A bungee jumper with a mass of 65.0 kg jumps from a high bridge. After reaching his lowest point, he oscillates up and down, hitting a low point more times in 38.0s. He finally comes to rest at 25.0m below the level of the bridge. Calculate the stiffness (Spring constant) and the unstretched length of the bungee cord.
