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 8.4 rad/s counterclockwise and an angular acceleration of 2.2 rad/s2 clockwise, determine the acceleration of

a. (round the final answer to two decimal places.)
