Chris jumps off a bridge with a bungee cord (a heavy stretchable cord) tied around his ankle. He falls for 15 mm before the bungee cord begins to stretch. Chris's mass is 72 kg and we assume the cord obeys Hooke's law, F=−kx, with 52 N/m
If we neglect air resistance, estimate what distance dd below the bridge Chris's foot will be before coming to a stop. Ignore the mass of the cord (not realistic, however) and treat Chris as a particle.
Express your answer to two significant figures and include the appropriate units

A 90 kg student jumps off a bridge with a 8-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 400 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?

An 80.0 kg bungee jumper drops from rest off a bridge that is 200.0 m above a river. As he falls, air resistance is negligible, and the unstretched bungee cord attached to him uncoils. The mass of the bungee cord is negligible. When the jumper is 50.0 m below the bridge, the bungee cord is completely uncoiled and forms a straight line. Below that point, the bungee cord acts as a spring, obeying Hooke's law as it is stretched beyond...

You sign up for a bungee jump off a tall bridge. A thick rope with a fixed length of 16.0 m is tied to the bridge, and a bungee cord with an unstretched length of 8.00 m is then connected to the rope. The other end of the bungee cord is attached to your legs. You step off the bridge, falling from rest. The bungee cord does not start exerting any force on you until you have fallen a distance...

5. In bungee jumping, it is obviously important to know in advance how far an elastic cord of un-stretched length L will stretch with a given weight attached to its end. In one model for this elongation, the cord is simply considered to be a weak spring with constant k and the person tied to the end of the cord is a point mass m. Air resistance and any pendulum motion of the cord mass system are ignored. Suppose a...

When bungee jumping from a high bridge over Victoria Falls, an operator first attaches an elastic rope to the jumper. The jumper then jumps off the bridge, falling freely until they reach the unstretched length of the rope Then, the rope begins to stretch and slows the jumper to a stop. The rope pulls the jumper back up, and they oscillate up and down for a while until the operator pulls the jumper back up to the bridge. The rope...
