An elastic cord is 61 cm long when a weight of 75 N hangs from it but is 85 cm long when a weight of 210 N hangs from it. What is the “spring” constant k of this elastic cord? also, find the frequency of the motion with the 210N object hanging on it (Physics 'Algebra base')

An elastic cord is 70 cm long when a weight of 80 N hangs from it but is 84 cm long when a weight of 200 N hangs from it. What is the "spring" constant k of this elastic cord? Express your answer to two significant figures and include the appropriate units.
A vertical elastic cord is stretched 0.306 m when a mass 1.66 kg is attached to...
A vertical elastic cord is stretched 0.306 m when a mass 1.66 kg is attached to it. The cord is then stretched an additional 0.114 m and released from rest. Assuming the cord is an ideal linear spring, how long does it take for the mass to reach its original equilibrium position? HINTS: First find the elastic constant of the elastic cord, using the fact that the gravitational weight mg of the mass is balanced by the upward pull of...

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

As indicated in the figure, a steel ball (m 200 g) is attached to a massless elastic cord which is initially not stretched. When the ball is released from rest at A, t slides without friction through a thin curved tube with constant radius of curvature r = 70.0 cm. The cord stretches as the ball slides down the tube and follows the curvature of the surface, as indicated by the thick dashed line in the figure. Furthermore, the cord...
