Problem \( 15.119 \) - Rigid body kinematics, relative velocity and acceleration The \( 200 \mathrm{~mm} \)-radius disk rolis without sliding on the surface shown. Knowing that the distance \( B G \) is \( 160 \mathrm{~mm} \) and that at the instant shown the disk has an angular velocity of 11 rad/s counterciockwise and an angular occeleration of \( 3.5 \) radis \( { }^{2} \) clockwise, determine the acceleration of \( \mathrm{A} \) The accelecation of \( A \) is
