A mass is connected by a light string that passes over a pulley of mass M to a mass sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of 1?2 If is 1.00 kg, is 2.00 kg, and M is 4.00 kg, then what is the acceleration of
