So I have a simple question about the speed of two cylinders going down a slope.
The speed of the hollow cylinder is: v = (gh)^0.5
The speed of the solid cylinder is v = (4/3gh)^0.5
So the solid always wins a race against the hollow. But I wonder how big must the hole in the cylinder be? Is it enough to make a hole with a nail to make it obey the hollow speed formula?
Cheers
