1. The problem statement, all variables and given/known data A 74.4-kg bungee jumper is standing on a tall platform (h0 = 46.6 m). The bungee cord has an unstrained length of L0 = 9.54 m and, when stretched, behaves like an ideal spring with a spring constant of k = 61.8 N/m. The jumper falls from rest, and it is assumed that the only forces acting on him are his weight and, for the latter part of the descent, the elastic force of the bungee cord. Determine how far the bungee jumper is from the water when he reaches the lowest point in his fall. 2. Relevant equations mghf+.5ky2=mgh0 3. The attempt at a solution No idea, made several attempts with results close to 10.
