Well, in the detailed answer Krotov has ignored Kinetic energy due to rotational motion completely.His final equation is mv^2/2 = mV^2/2 - mgr(1-cosx). Anyways, moment of inertia of solid cylinder and disk are same

Homework Statement I have attatched both the problems. The figure is essentially the same. Homework Equations 1. Energy conservation 2.mgcosx - N = mv^2/r , where N is zero in limiting case. The Attempt at a Solution I solved the whole question and got the answer given in irodov(0.33...
