Member $AB$ has the angular velocity ${}_{AB}=3\mathrm{.}5ra\frac{d}{s}$ and

angular acceleration ${}_{AB}=9ra\frac{d}{s^2}.($Figure $1)$

Figure

$1$ of $1$

Determine the angular velocity of member $CD$ at the instant shown 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.

${}_{CD}=$

$ra\frac{d}{s}$

Part B

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

Express your answer using three significant figures. Enter positive value if the angular acceleration is counterclockwise and negative value if

the angular acceleration is clockwise.
