Homework Help: Gravitational Potential Energy of a box

  1. Feb 12, 2010 #1
    1. The problem statement, all variables and given/known data

    a 18.5 kg box is slid up a 5.6 m 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?

    m = 18.5 kg
    d = 5.6 m
    http://musr.physics.ubc.ca/~jess/symbols/Theta.gif = 33°
    PEg = ?


    2. Relevant equations

    Eg = mgh

    I think. haha


    3. The attempt at a solution

    I have absolutely no idea. I am hoping someone on here could get me started with this question, not give me the answer, but just get me started. Thanks.

    You are right about [tex]E_{gp}=mgh[/tex]. Height [tex]h[/tex] is the only problem and it can easily be obtained by using trigonometry.
