Say you set up an experiment with an inclined plane, and a cylinder rolling down the plane. Let's also let the experiment happen in a vacuum, such that there is no air friction.

However, let there be friction between the surface of the incline and the cylinder.

My questions related to this are;

does the cylinder accelerate forever? or does the cylinder have a terminal velocity? Does the cylinder keep rolling forever, or is it the case that, at some point, it starts slipping?

In an idealized, Newtonian world (infinite inclined plane in an infinite, uniform gravitational field, infinite strength and stiffness of cylinder material, etc.) it would accelerate forever.
