**1. Ut will bungee jump from the golden gate bridge. The height that she will jump from is 65 meters. The rope pulls her up 8 meters above the water. If UT's weight is 63 kg, how far will the rubber rope pull her upwards, if there's no loss to friction or air resistance?**

## Homework Equations

PE= mgh

v=√2gh

v^2-u^2=2as

3. The Attempt at a Solution

I started by calculating the energy of the fall.

PE= 63*(65-8)*9.8= 35191 J

I then tried to calculate the velocity that she reaches when she is about to fall.

v=√2gh= 33.45 m/s

I then used v^2-u^2=2as, u^2 at the top is 0 and a= g=9.8 and s=h

v^2-u^2=2as

33.45^2-0= 2*9.82* s

s= 55.4 meters

That seems oddly wrong that she could reach such a height, is this the right way to do it or is there a mistake?
