## Homework Statement

[PLAIN]http://img8.imageshack.us/img8/664/photo4dc.jpg [Broken]

Sorry it is sideways.

Only known data is the 6m drop from the 12m high ledge.

## Homework Equations

Currently wokring with Kinetic enery (1/2mv^2), potential energy(mgh).

## The Attempt at a Solution

My thinking is mass doesnt matter, it will cancel out due to the mechanical energy( if that makes sense). Therefore the equation to solve is v

^{2}

_{f}=2gh

Therefore after subbing in 9.81m/s

^{s}for g, 6m for h; my final answer is 11m/s with rounding because of sig figs.

Thank you for help
