Conservation of energy to find horizontal displacement?

  1. Sep 18, 2011 #1
    1. The problem statement, all variables and given/known data

    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?

    2. Relevant 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.
