Hey yall, I have a question that is totally stumping me, and I have no idea where to start. I would appreciate it if someone could help me on it. Thanks in advance.

Here is the question:

In the dangerous sport of bungee-jumping, a daring student jumps from a balloon with a specially designed elastic cord attached to his ankles. The unstretched length of the cord is 25.0 m, the student weighs 700 N, and the balloon is 36.0 m above the river below. Assuming that Hooke's law describes the cord, calculate the required force constant if the student is to stop safely 4.0 m above the river.

What I have is below.

Thanks
