Learning Goal: A bungee jumper wants to jump off the edge of a bridge that spans a river below. The jumper has a mass m, and the surface of the bridge is a height h above the water. The bungee cord, which has length L when unstretched, will first straighten and then stretch as the jumper falls. Assume the following: . The bungee cord behaves as an ideal spring once it begins to stretch and has spring constant k. The jumper does not actually jump but simply steps off the edge of the bridge and falls straight downward. The jumper's height is negligible compared to the length of the bungee cord. Thus, the jumper can be treated as a point particle.

Bungee Jumping
Learning Goal:
A bungee jumper wants to jump off the edge of a bridge that spans a
river below. The jumper has a mass m, and the surface of the bridge
is a height h above the water. The bungee cord, which has length L
when unstretched, will first straighten and then stretch as the jumper
falls.
Assume the following:
• The bungee cord behaves as an ideal spring once it
begins to stretch and has spring constant k.
•
The jumper does not actually jump but simply steps off
the edge of the bridge and falls straight downward.
The jumper's height is negligible compared to the length
of the bungee cord. Thus, the jumper can be treated as a
point particle.
Use 9
for the magnitude of the acceleration due to gravity.
