The Royal Gorge bridge over the Arkansas River is 310.0 m above the river. A 59.0-kg bungee jumper has an elastic cord with an unstressed length of 62.0 m 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
