A bungee jumper makes a jump into the Gorge du Verdon in the southern France from a platform 182 m over the bottom of the gorge. The jumper weighs 740 N and comes in 67 m of the bottom of the gorge. The cord's un-stretched length is around 30.0 m.
Supposing that the bungee cord follows Hooke's law when it stretches; determine its spring constant.
At what speed is the jumper falling if he reaches a height of 93 m over the bottom of the gorge?
