Question

need help for c, e, and f please! work

A 60.0 kg bungee jumper steps off a bridge with a light bungee cord tied to her and to the bridge. The unstretched length of the cord is 15.0 m. She reaches the bottom of her motion 40.0 m below the bridge before bouncing back. Her motion can be separated into an 15.0 m free-fall and a 25.0 m section of simple harmonic oscillation Mail awong12@mail.stsu.edu (a) For what time interval is she in free-fall? 1.75 (b) Use the principle of conservation of energy to find the spring constant of the bungee corc 75.3 (c) What is the location of the equilibrium point where the spring force balances the gravitational force acting on the jumper? Note that this point is taken as the origin in our mathematical description of simple harmonic oscillation N/m Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, m below the bridge (d) What is the angular frequency of the oscillation? 1.12 (e) What time interval is required for the cord to stretch by 25.0 m? rad/s beginning and check each step carefully.s (f) What is the total time interval for the entire 40.0 m drop? Your response differs from the correct answer by more than 100%. S

Explanation / Answer

Solution) e)We have time period T=2(pi)(l/g)^(1÷2)

T=2×3.14×(25/9.8)^(1÷2)

T=10.03seconds

f) We have time period T=2(pi)(l/g)^(1÷2)

T=2×3.14×(40÷9.8)^(1÷2)

T=12.68seconds
