A quick return mechanism is designed to give a slow forward motion $($cutting stroke$)$ and a quick return of the

slider at $C.$ the link $AB$ is rotating at $=3ra\frac{d}{s}$ and $=1\mathrm{.}5ra\frac{d}{s}.$ At the instant shown, determine the

$($a$)$ velocity vector of point $B$

$($b$)$ velocity vector of slider $C$

$($c$)$ the angular accelerations of the rod $CB$
