Question

The Royal Gorge bridge over the Arkansas River is 310 m above the river. A 56-kg bungee jumper has an elastic cord with an unstressed length of 57 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 in km

(b) Find the maximum speed of the jumper in m/s

Explanation / Answer

With outstretched arm, the lady might be supposed to be about 2m tall. However you don
