The crank AB is rotating counterclockwise at a constant angular velocity of 12 rad/s while the pin B slides within the slot in the bar CD, which is pinned at C. Letting R = 0.5 m, h = 1 m, and d = 0.25 m, determine the angular velocity of CD at the instant shown (with points A, B, and C vertically aligned) as well as the velocity of the horizontal bar to which bar CD is connected.
