Two bricks each with masses m are connected by a massless cord over a uniform cylindrical pulley with mass m and radius r as shown in the figure. There is static friction between the cord and the pulley such that motion of the bricks causes the pulley to rotate in its frictionless bearing. One brick hangs vertically from the pulley, the other moves on a 30o inclined frictionless plane.Determine the direction and magnitude of the acceleration of the bricks
