a small cylinder of radius r is released coaxially from point A inside the fixed large cylindrical bowl of radius r as in fug.if the friction between the small and large cylinder is sufficient enough t o prevent any slipping then find (a) the fractions of total KE vs rotational when the cylinder reaches the bottom .(b) the normal force exerted by small cylinder on the larger one when it is at bottom.

in part 1 question ask this: \[(0.5mv ^{2}+0.5\omega ^{2})/(0.5I \omega ^{2})\] so v=Rw i think ithink answer is:2[(R/r)]^2
