The uniform plate weighs 40lb and is supported by a roller at A. If a horizontal force of F = 70 lb is applied to the roller, determine the acceleration of the center of the roller at the instant the force is applied. The plate has a moment of inertia about its center of mass of I_G = 0.414 slug · ft². Neglect the weight and the size d of the roller.
