Question

Tom D. spends his spare time running a bungee jumping service off the Henley Street bridge. He has a 120 ft long bungee cord (un-stretched) that has a spring stiffness of 24 lb/ft. To test his bungee, he ties the bungee cord to the bridge railing, ties the other end to an unnamed person weighing 123 pounds, and then gently nudges the person off of the bridge.

the person's speed when the bungee cord starts to stretch= 87.91 ft/sec

B) Assuming they haven't hit the water, how much has the bungee chord stretched when the person is at the bottom of the jump? (include units with answer)
