For the system shown in Fig., m 1 = 8.0 kg, m 2 = 3.0 kg, = 30°, and the radius and mass of the pulley are 0.10 m and 0.10 kg, respectively. (a) What is the acceleration of the masses (Neglect friction and the string's mass.) (b) If the pulley has a constant frictional torque of 0.050 m · N when the system is in motion, what is the acceleration of the masses [ Hint : isolate the forces. The tensions in the strings are different. Why ]
