A bungee cord is essentially a very long rubber band that can stretch up to four times its unstretched length. However, its spring constant varies over its stretch [see Menz, P.G. “The Physics of Bungee Jumping.” The Physics Teacher (November 1993) 31: 483-487]. Suppose an unstretched bungee cord has a length l0 = 23.3 m and during a bungee jump it stretches so that its maximum total length is l = 53.7 m. Suppose that bungee cord behaves like an...
Pierce is bungee jumping off of the top of a 75 meter tall dam in Russia with a cord that is too long
Pierce is bungee jumping off of the top of a 75 meter tall dam in Russia with a cord that is too long. When he splashes into the water at the bottom of the dam he is moving at a speed of 8.0 m/s, and the bungee cord is stretched to be 25 m longer than its rest length. If the bungee cord has a spring constant of 160 N/m, what is Pierce's mass in kilograms? (Ignore air resistance)

4./Your adventurous friend Lola goes bungee jumping. She leaps from a bridge that is 100 m above a river. Her bungee cord has an un-stretched length of 50 m and a spring constant k - 600 N/m. Lola has a mass of 48 kg. How fast is she falling when she just starts to stretch the cord? How long does it take for Lola to reach this point? a) Lola stretches the bungee cord and it brings her to a...

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?

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...

A 75 g bungee cord has an equilibrium length of 1.2 m. The cord is stretched to a length of 1.8 m, then vibrated at 20 Hz. This produces a standing wave with two antinodes. What is the spring constant of the bungee cord (in N/m)?

Bungee Jumping (Springs) RATE LIFESAVER!!
Kate, a bungee jumper, wants to jump off the edge of a bridge thatspans a river below. Kate has a mass m, and the surface of thebridge is a height h above the water.The bungee cord, which haslength L when unstretched, will first straighten and then stretchas Kate falls.Assume the following:? The bungee cord behaves as an ideal spring once it begins tostretch, with spring constant k.? Kate doesn't actually jump but simply steps off the edge of thebridge and...
