Conservation of energy to find horizontal displacement?

[goomer]

Homework Statement

This probably seems really obvious but what formula do you use to find velocity with conservation of energy? Once you find the velocity, is it the velocity of the object at the bottom of the height?

Homework Equations

This is what I'm not sure about. Is it mgh=0.5mv^2?

The formula depends on the situation! The formula you wrote in your last line applies to a situation where an object is falling from rest, converting all of its potential energy into kinetic energy.
