A bungee jumper makes a jump into the Gorge du Verdon in southern France from a platform 182 m above the bottom of the gorge. The jumper weighs 740 N and comes within 66 m of the bottom of the gorge. The cord's unstretched length is 30.0 m.

(a) Assuming that the bungee cord follows Hooke's law when it stretches, find its spring constant. [Hint: The cord does not begin to stretch until the jumper has fallen 30.0 m.](in N/m)

(b) At what speed is the jumper falling when he reaches a height of 95 m above the bottom of the gorge?(in m/s)
