# Work, Energy & Power

Please help with the following problem.

A Bungee Jumper jumps off of height H and just reaches the bottom of the cliff with a zero velocity. Just before her cable snaps her back upward, while she is motionless, she grabs a rock of mass m1.

You observe that the jumper achieves the height h on the way back up. What is m1?

When you evaluate, consider the cases h=H and h=0
