Homework Statement
A daring friend of yours talks you into bungee jumping from the Royal Gorge Bridge, in Colorado. Starting from the bridge (at rest), you launch off and fall first to the unstretched length of the bungee, 153 m. The bungee then stretches until you reach the full drop distance of 321 m. For this problem, approximate your mass as 70 kg.
a. What is the energy stored (or lost) by the bungee?
b. After you drop the full distance, you bounce back up to 50 m below the launch point. How much energy was lost (to air friction and heat) in the first drop?
Homework Equations
PE=mgh
The Attempt at a Solution
Part A) mgh = 70*9.8*321 lost
Part B) 70*9.8*321 - 70*9.8*(321-50)
