The royal gorge bridge over the arkansas river is 393 m above the river. a bungee jumper of mass 150 kg has an elastic cord of length 78 m attached to her feet. assume the cord acts like a spring of force constant k. the jumper leaps, barely touches the water, and after numerous ups and downs comes to rest at a height h above the water. the acceleration of gravity is 9.81 m/s². find h. answer in units of m.
