Explanation
Change in speed is zero as speed is scalar.
The M.I. is minimum about EG because mass distribution is at minimum distance from EG.
A couple produces only rotational motion.
Moment of inertia depends on mass of the body.
As size of the handle piece is bigger, its mass will be smaller i.e. mass of bottom piece of bat will be larger.
Theory [2] The centre of mass of lucky remains uncharged.
Angular speed for both wheels are different but lincar speed for both same so VF = Vr
