... Answer: KE increases. Although L=constant, the ant does positive work in pushing the mass toward the center. The work-energy theorem says KE=Wnet. So the KE of the ant+disk increases. Suppose the disk was on a phonograph player, so that it always turned at 33 rpm. As Atom-Ant moves inward, the spee ...
