At a given instant, rod $BD$ is rotating about the $x$ axis with an angular velocity ${}_{BD}=2ra\frac{d}{s}$ and an angular acceleration ${}_{BD}=5ra\frac{d}{s^2}.$ Also, when $=45$ link $AC$ is rotating at ${}^{}=4\mathrm{.}5ra\frac{d}{s}$ and ${}^{}=2ra\frac{d}{s^2}$ as shown in $($Figure $1).$ Assume $AC=6\mathrm{.}5ft.$

Determine the $x,y,$ and $z$ components of the velocity of point $A$ on the link at this instant.

Express your answers in feet per second using three significant figures separated by commas.
