Here's the question you clicked on:
AravindG
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.
do you use conservation law of E? between A& bottom point
in point A it has PE & in bottom has KE (rotational & transitional KE) do you get my goal?
\[mgr=(1/2mv ^{2})+(1/2)I \omega ^{2}\]
for sylender \[I=(1/2mr ^{2})\]
from 2nd law of newton have \[N-mg=mv ^{2}/R\] right?
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
sorry one of the i think is lampoon
big cylender is frictionless ok?
i answered part b on top
