The 10-lb bar is on a smooth horizontal table The figure shows the bar viewed from above. Its moment of inertia about the center of mass is I -0.8 slug-ft2. The bar is stationary when the force F = 5 lb is applied in the direction parallel to the y axis. At that instant, determine (a) the acceleration of the center of mass, and (b) the acceleration of point A.
