Disk D$,$ of radius r$=0\mathrm{.}5$m$,$ rolls without slipping on a

horizontal floor with a constant clockwise angular

velocity. Rod R$,$ is hinged to disk D at A$,$ and the end of

the rod B$,$ slides along the floor. Determine the angular

velocity of rod R when the line OA joining the center of

the disk to the hinge at A is horizontal as shown. For

the instant shown, the x and y components of the

velocity of point A are $2\mathrm{.}5$m$//$s and $2\mathrm{.}0$m$//$s

respectively.

Is the angular velocity of the rod R clockwise $($CW$)$ or

counter$-$clockwise $($CCW$)?$ Please type either CW or

CCW$.[$a$]$ also the correct answer is $1$ rad$/$s CCW or $1$ radian$/$s counter clockwise please explain why it is
