# Question

For the system shown in Fig. 8.48, m1 = 8.0 kg, m2 = 3.0 kg, θ = 30o, 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?
