] A 2-kg block and a 5-kg block are attached to opposite ends of a massless rope. The rope hangs over a solid, frictionless pulley that has a diameter of 40 cm and a mass of 4 kg. When the blocks are released, a 5-N force of air resistance opposes the motion of each block. Determine the acceleration of the system
