Two masses are suspended from a pulley as shown in Fig. 8.47 (the Atwood machine revisited; see Chapter 4, Exercise 55). The pulley itself has a mass of 0.20 kg, a radius of 0.15 m, and a constant torque of due to the friction between the rotating pulley and its axle.

What is the magnitude of the acceleration of the suspended masses if m1 = 0.40 kg and m2 = 0.80 kg? (Neglect the mass of the string.)
