Problem $15\mathrm{.}119-$ The acceleration of $A$

The $200-$mm$-$radius disk rolls without sliding on the surface shown. Knowing that the distance $BG$ is $160$ mm and that at the instant shown the disk has an angular velocity of $8\mathrm{.}600ra\frac{d}{s}$ counterclockwise and an angular acceleration of $2\mathrm{.}300ra\frac{d}{s^2}$ clockwise, determine the acceleration of $A.$

The acceleration of $A$ is: $\frac{m}{s^2}$I
