If you're looking for the motion of a rolling cart, the cart is the object of interest. Draw a sketch! This may help you sort out which object is which in your problem

I assume the object of interest is rolling down a slope so there would be a couple of things, 'of interest' including the slope.

a=g sin(angle theta)

Ok, wait here and I'll figure this out for you. Did you want the sketch done in pen or pencil? Or does it not matter?

odinn7, I want you to draw a cart with a rock in it going uphill, pulled by Sisyphus.

Ok, I'll add that to my list. When I am done drawing out the diagram for the OP, I still have 6 others to get to before your request. I am drawing these up in AutoCAD so I will be sure that they are accurate and true to scale.
