Two scenes for a research project

[dearprudence101]

Hello all,

 

I'm new to the forums. I have to create two simple scenes depicting a sphere rolling down a ramp and passing behind an occluder before reappearing. My ramp was made by extruding a line. How do I connect the sphere to follow the path of the ramp? Also how do I make it rotate?

 

I've tried to use path constraint from the modifer list, but it wouldn't allow me to choose the ramp as a pathway. What would be the next step?

 

Thanks
