Problem $16\mathrm{.}118-$ Enhanced $-$ with Hints and Feedback

Determine the angular velocity of member CD at the instant shown measured counterclockwise.

Express your answer in radians per second to three significant figures. Assume the positive direction is counterclockwise.

Member AB has the angular velocity $\backslash$omega $\_($AB$)=2$ra$($d$)/($s$)$ and

angular acceleration $\backslash$alpha $\_($AB$)=7$ra$($d$)/($s$^(2)).($Figure $1)$
