Q$2.$ If the velocity of the center $O$ of the rolling disk without slipping is $50c\frac{m}{s}$ towards right for the instant shown, determine the angular velocity of bar $AB,{}_{AB},$ and the velocity of end $B,v_B,$ of rodAB, which slides in the circular slot by using the Method of Instantaneous Center of Zero Velocity. $$ grades will be given if solved by using another method.
