???????

At the instant shown, \( \theta=60^{\circ} \), and rod \( A B \) is subjected to a deceleration \( a=18 \mathrm{~m} / \mathrm{s}^{2} \) when the velocity \( v=12 \mathrm{~m} / \mathrm{s} \). (Figure 1) Determine the angular velocity of link \( C D \) at this instant measured counterclockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is counterclockwise and negative value if the angular velocity is clockwise.
