The slotted bar is rotating with angular velocity

$\backslash$omega $=\backslash$theta $^()=3\mathrm{.}5$ra$($d$)/($s$)$ and angular acceleration

$\backslash$alpha $=\backslash$theta $^()=4$ra$($d$)/($s$)$ at this instant when $\backslash$theta $=45\backslash$deg $.$ The

distance b$=1$m$.$

What's the velocity of pin A at this instant.

v$\_($A$)=5$i$+7$j$($m$)/($s$)$

v$\_($A$)=4$i$+6$j$($m$)/($s$)$

v$\_($A$)=0$i$+7$j$($m$)/($s$)$

v$\_($A$)=5$i$+0$j$($m$)/($s$)$
