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)?
A cord used in bungee jumping is normally 9.88 m long and has spring constant k = 299 N/m. At the lowest point in a jump, the cord length has doubled. How much work has been done on the cord?
A cord used in bungee jumping is normally 9.88 m long and has spring constant k = 299 N/m. At the lowest point in a jump, the cord length has doubled. How much work has been done on the cord?
A 70 kg person does a bungee jump from a bridge. The natural length of the bungee cord is 20m and it has a spring constant k of 80 N/m. When the bungee cord has a total length of 25m, what is the acceleration of the jumper (to 2 significant figures)?
A bungee jumper of mass 75kg is attached to a bungee cord of length L=35m. She walks off a platform (with no initial speed), reaches a height of 72m below the platform, and continues to oscillate. While air resistance eventually slows her to a stop, assume there is no air resistance for these calculations. 1. What is the spring constant of her bungee cord? 2. What is her speed when she is 35m below the platform (i.e., just before the...
7. A bungee cord of mass m and length Lis stretched to a length of 5L/4 and then vibrated at a frequencyf, producing a standing wave with four antinodes. A. (5 points) Include a diagram showing the original cord, the stretched cord and the standing wave B. (20 points) What is the spring constant of the cord?
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...
Review Part A A 67 g bungee cord has an equilibrium length of 1.20 m. The cord is stretched to a length of 1.80 m, then vibrated at 23 Hz. This produces a standing wave with two antinodes. What is the spring constant of the bungee cord? Express your answer to two significant figures and include the appropriate units.

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
