Help with a few problems, asap. Thanks In Advance

I am trying to achieve 2 collision shapes in specific points and am unsure how i should go about it.

One shape is the top of a spring, the other is a conveyor belt.

Here is an image that shows what I am trying to do in proper detail

Also out of curiosity, i have my object interacting with the spring just as i want, but am unsure what is the best way to handle the conveyor belt interaction? I am currently using transition.to, but im sure there is a physics way of doing this. My spring interaction is handled by a applylinearvelocity call.

If anyone would check out the picture and give me some help i would really appreciate it as this is the only issue I am having in completing my game. The last stumbling block if you like.
