Main Question or Discussion Point
A disc and a hoop (ring) both of same mass and radius roll down an inclined plane of height "h". It is well known the disc has great velocity than that of the hoop at the bottom. I am fixed in the situation after they start rolling horizontally. Which will go farther? If the surface is frictionless, none will start and there is no question of stopping. But if they face friction, then I assume both will face same friction and same torque caused by this friction because they have same mass and radius. I can't quite figure out which will stop first and why? Please help.
