The Royal Gorge bridge over the Arkansas River is above
Chapter , Problem 53(choose chapter or problem)
The Royal Gorge bridge over the Arkansas River is above the river. A 60-kg bungee jumper has an elastic cord with an unstressed length of attached to her feet. Assume that, like an ideal spring, the cord is massless and provides a linear restoring force when stretched. The jumper leaps, and at at her lowest point she barely touches the water. After numerous ascents and descents, she comes to rest at a height h above the water. Model the jumper as a point particle and assume that any effects of air resistance are negligible. (a) Find h. (b) Find the maximum speed of the jumper.

(b) Find the maximum speed of the jumper.
ANSWER:Step 1 of 4
The initial energy of the jumper is,
For, 
From the conservation f energy,
