The disk rolls without slipping such that it has an angular acceleration of $=8$ rad$/$s$2$rad$/$s$2$ and angular velocity of $=2$ rad$/$srad$/$s at the instant shown. Assume point A lies on the periphery of the disk, $150$ mm from C$.$ Determine the magnitude of the acceleration of point A on the link. Determine the direction of the acceleration of point A on the link. Determine the acceleration of point B on the link. Determine the link's angular acceleration at this instant.
