1. The problem statement, all variables and given/known data You have persuaded your friend Astrid to attempt an illegal bungee jump from the New River Gorge Bridge. You will provide the bungee cord which has a total length of 40 m and a spring constant of k = 16 N/m. During the jump, Astrid will first fall freely for a distance equal to the length of the cord, after which the cord will begin to stretch, obeying Hooke’s law. Astrid’s mass is 52 kg. The lowest point she reaches before rebounding is _____________ below the bridge. 2. Relevant equations No idea really, but I assume: f=kx PE=1/2kx^2 PE=mgh KE=1/2mv^2 3. The attempt at a solution So I found the velocity she has right when the bungee is at it's normal length of 40m, but I have no idea where to go from there. The velocity I calculated was 28m/s, and that might not be right.
