Homework Statement


A bungee jumper with a mass of 77.0kg, jumps from a high bridge. He just touches the water in the river below and after reaching this lowest point, he oscillates up and down, hitting the lowest point another 8 times in 48.0 seconds. Calculate the spring constant of the bungee cord.

Homework Equations


F = -kx
T = 2π√(m/k)


The Attempt at a Solution


I thought the period was 6 (48/8) and then used those two equations to solve for k. Got 8.94 but Im not sure if I did it right...

You know the period and mass you can solve for the spring constant directly from the period equation. Check your math.
