wow thanks! That helped a lot.

The only thing is (sorry i didn't make it clear) but my "ramp' is horizontal. So it just moves back and forth.
Well, I did not know what an air-hockey style ramp looks like. But why did you say that the cart starts at the top if the ramp is horizontal? That is why you should attach a figure to such questions.
If the cart moves only horizontally, everything is much easier.
