A 75 kg mountain climber hangs stationary from a bungee cord over a steep incline of 80◦ (nearly a vertical wall). The bungee cord has a Hooke constant of k = 550 N/m and is parallel to the incline.

(a) If the climber has a coeﬀicient of friction μs = 0.9 with the incline, how much will the rope deform? Assume that the maximum amount of friction (and thus the minimum deformation).

(b) Suppose the climber loses their grip, reducing this coeﬀicient to only μs = 0.1. Once they come to a stop, what is the rope’s new deformation? Again assume the maximum amount of friction.

A person is bungee jumping. The bungee cord is attached to a bridge over a river. At time t0, before the person jumps (and while she is at rest), the bungee cord is unstretched. At time t1, the cord is stretched and the person is moving downward at her maximum speed. At time t2, the person has fallen her maximum distance and the cord is stretched by its maximum amount. At t3, the person is moving back up toward the...

A 74.0-kg bungee jumper steps off a bridge with a light bungee cord tied to her and to the bridge. The unstretched length of the cord is 14.0 m. The jumper reaches reaches the bottom of her motion 40.0 m below the bridge before bouncing back. We wish to find the time interval between her leaving the bridge and her arriving at the bottom of her motion. Her overall motion can be separated into an 14.0-m free-fall and a 26.0-m...

An 85.4-kg climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves like a spring with a spring constant of 1.19 103 N/m. He accidentally slips and falls freely for 0.815 m before the rope runs out of slack. How much is the rope stretched when it breaks his fall and momentarily brings him to rest?

A 90 kg student jumps off a bridge with a 10-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 390 N/m. You can assume that the bungee cord exerts no force until it begins to stretch. How far below the bridge is the student's lowest point? How far below the bridge is the student's resting position after the oscillations have been fully damped?
