Finally, the center of rotation theorem:

In each case, find the angular accn. of the rigid body assuming that it rolls without slipping at pt. of contact with plane or thread...

and observe....


Post your answers for M=2;m=1;R=2;r=1 AND K=1/2;


the answers are not important,; i want an observation...a weapon with which you can solve all questions with a center of rotation simply by lookin at them...


Expect 10 more such problems tomorrow...
