What is the gravitational potential energy of the box relative to the floor?

[nicolehoskins]

Homework Statement

An 18.5kg box is slid up a 5.6m long ramp that makes an angle of 33 degrees with the floor. What is the gravitational potential energy of the box relative to the floor?

Homework Equations

E_k = 1/2mv²

The Attempt at a Solution

My teacher gave me an answer of 550J, but I'm not sure how to show my work

Welcome to PF!

What determines the amount of gravitational potential energy of an object? You wrote an equation for kinetic energy, but that is not relevant here.

Well, you can type it into the reply box. If you need to use special math symbols or Greek letters, you can hit the big ∑ button on the reply box toolbar or use Latex.

Whoops, I meant E_g = mgh

Ok so m and g are easy. All you need to do is calculate h.
