1. The problem statement, all variables and given/known data

American advertising agency McKAnn decided to bungee jump a car off a bridge to show how well made the car was. They used a 30 m m rubber bungee cord used by the army to bungee tanks during air drops. it had nine individual cords each around 12cm in diameter. when released from the top of the bridge , 267m above the water , the 1857kg ute stretched the cord 6* its original length. Calculate the spring constant of the cord. (k)

2. Relevant equations

F=-kx

forces and spring equations.

3. The attempt at a solution

I have found the area of the bungee to be .135717m^2, also i can calculate the GPE but that is as far as i have gotten- please help. the answer is 254 N M
