A certain unstretched bungee cord is 26 m long. A 73 kg person attaches one end of the cord to himself and the other end to the top of a 782 m high bridge. He then slowly lowers himself from the bridge.What must the spring constant of the cord be so that the person is just barely touching the ground when the cord is fully stretched?

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...

A 84.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 105 N/m, and the system's damping constant is 0.137 kg/s. How long does it take for the oscillation amplitude to decrease to 90.6 % of its initial value? time: s What is the frequency of oscillation? frequency: Hz

A 64.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 1.10×102 N/m, and the system's damping constant is 0.116 kg/s. How long does it take for the oscillation amplitude to decrease to 93.1 % of its initial value? time: s What is the frequency of oscillation? frequency: Hz

A bungee cord is 30.0 m long and. when stretched a distance x, it exerts a restoring force of magnitude kx. Your father-in-law (mass 100 kg) stands on a platform 45.0 m above the ground, and one end of the cord is tied securely to his ankle and the other end to the platform. You have promised him that when he steps off the platform he will fall a maximum distance of only 41.0 m before the cord stops...

Your 60 kg friend is bungee jumping from a bridge which is 60 m high. She falls a distance of 25 m before her bungee starts to stretch. -If she starts from rest at the top of the bridge, what is her change in kinetic energy (in kJ) right before her bungee begins to stretch? -If the bungee brings her to a stop when she is just about to to hit the ground (has fallen a distance 60 m), what...

A 68 kg bungee jumper is standing on a platform 46 m above the ground. The jumper falls from rest and it is assumed that the bungee cord, which is attached to the bungee jumper at one end and the platform at the other, has no effect for the first 9 m of the fall, i.e. the natural length of the cord is 9 m. When the bungee jumper is more than 9 m away from the platform the cord...

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...
