The slider block $C$ moves at $9\mathrm{.}5\frac{m}{s}$ down the inclined groove.

Determine the angular velocity of link $AB$ at the instant shown measured clockwise.

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

counterclockwise.

${}_{AB}=$

$ra\frac{d}{s}$
