Bungee Jumping.
A bungee jumper jumps from a tall bridge attached to a light elastic cord (bungee cord) of unstretched
length L. The cord first straightens and then extends as the jumper falls. This prevents
her from hitting the water! Suppose that the bungee cord behaves like a spring with spring constant
k = 100 N/m. The bridge is h = 100 m high and the jumperís mass is m = 50 kg.
a) What is the maximum allowed length L of the unstretched bungee cord to keep the jumper
alive? (Assume that the spring constant doesnít depend on L).
b) Before jumping, our jumper verified the spring constant of the cord. She low
