Two blocks, with masses m and 3m, are attached to the ends of a string with negligible mass that passes over a pulley, as shown above. The pulley has negligible mass and friction and is attached to the ceiling by a bracket. The blocks are simultaneously released from rest. The acceleration of the center of mass of the blocks-string-pulley system has magnitude aCOM . Briefly explain, in terms of any external forces acting on the system, why aCOM is less than g.
