    Vector Problem

    I don't really understand what they are asking here. Can somebody help?

    A block weighing 20 pounds rests on an inclined ramp that makes an angle of 18 degrees with the horizontal. Determine the components of the weight parallel and perpendicular to the ramp.

    I know how to find the vertical and horizontal components, but this isn't what they are looking for. How do I find the components that are parallel and perpendicular to the ramp? I can tell you that the answers are 6.2 and 19 pounds, respectively, but I have no idea how to do the math.

    Thanks.

    Thanks for the diagram. This is pretty much how I had envisioned the problem, but this helped get me unstuck. Thanks again!
