Sir what if there is a tilted disc in place of sphere then how to find KE of disc??? I think we can't apply 1/2(I)w^2 formula there because its not principle axis of rotation.

why didn't you take translation k.E. into account?

Sir when writing the kinetic of sphere at vertical AOR through point O, at time of writing of moment of inertia, shouldn't we write it is 2/5 mr^2 + m(R+r) ^2 ?

Sir.Why wasn't linear (translational) kinetic energy considered

Won't we also have to take the translation kinetic energy of the sphere as it is in pure rolling motion?

why we havn't took the linear energy of com i.e 1/2 m v-square

Ans 1 ->

NO... as R is the radius of circle in which centre of sphere is moving...
