## AravindG Group Title 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. 2 years ago 2 years ago

do you use conservation law of E? between A& bottom point

3. AravindG Group Title

?

4. hosein Group Title

in point A it has PE & in bottom has KE (rotational & transitional KE) do you get my goal?

5. hosein Group Title

$mgr=(1/2mv ^{2})+(1/2)I \omega ^{2}$

6. AravindG Group Title

ys

7. AravindG Group Title

then?

8. hosein Group Title

for sylender $I=(1/2mr ^{2})$

9. hosein Group Title

wait please...

10. hosein Group Title

from 2nd law of newton have $N-mg=mv ^{2}/R$ right?

11. hosein Group Title

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

12. hosein Group Title

sorry one of the i think is lampoon

13. hosein Group Title

big cylender is frictionless ok?

14. hosein Group Title

i answered part b on top
