## Homework Statement

A child and sled with a combined mass of 50.0 kg slide down a frictionless hill. If the sled starts from rest and has a speed of 12.0 m/s at the bottom, what is the height of the hill?

## Homework Equations

KE = 1/2 m v^2

PE = mgh

## The Attempt at a Solution

KE = 1/2 (50.0) (12.0^2)

KE = 3600 N

No idea what to do. :(
