Re: When Physical Intuition Fails

At some time the increasing forward linear speed of the wheel will equal the
decreasing tangential speed of the rim (R x omega). This will be the end of slippage.

There's an interesting linear problem that addresses the same issue. Drop a package
onto a moving conveyor belt. The package will slip (and accelerate) until it reaches
the speed of the belt - thereafter it moves at the speed of the belt.
