An Atwood machine is represented in figure where the pulley is in disc form and its moment of inertia is ImR. Here, m = 2 kg is the mass of the pulley and Ro 20 cm is the radius of the pulley. Initially the masses M₁ = 1 kg and M2 = 3 kg are kept at rest and released at time, t = 0. The direction of z-axis is out of the page. Ignore friction on the axis of rotation. Take g = 10 m/s². 11. What is the magnitude of the acceleration a of the masses in unit of m/s²? (a) 20/3 (b) 2 (c) 4 (d) 5 (e) 10/3 12. What is the ratio of the tensions, T₁/T2, shown in the figure? (a) 5/3 (b) 5/7 (c) 3/5 (d) 3/2 (e) 7/9 13. What is the angular speed, w, of the pulley at t=2 s, in unit of rad/s ?
