Do they each stretch a distance x? So the double spring stretches 2x, and F=2kx, and the k of the 2 ropes is half the k of one shorter rope?

Hello, thanks a lot for your help :-) So if I understand well when the jumper is hanging at equilibrium I should use Newton to find k? Sum of forces = kx-mg => k= mg/x But I'm still lost about the other part of the problem, because now there are 2 things I don't know (the spring constant for the...

Homework Statement A daredevil plans to bungee jump from a balloon 65.0m above the ground. He will use a uniform elastic cord, tied to a harness around his body, to stop his fall at point 10.0m above the ground. Model his body as a particle and the cord as having negligible mass and obeying...
