Blocks A & B are connected through an inextensible cord which is wrapping over the uniform pulley, hence treated as an uniform disk, as shown. The masses of the blocks and pulley are $=30$ kg$,=10$ kg$,$ and $=3$ kg$.$ The radius of the pulley, $=1$ m$.$ If the blocks are released from rest, determine the velocity and acceleration of the block A $($ and $),$ angular velocity and angular acceleration of the pully $($ and $),$ tensions in the left and right segments of the cord $($ and $)$ and the reaction force at O $()$ after the block B has moved $10$ m downward. There is no slip between the cord and the pully.
