Fig. 1 shows two blocks connected by a light cord that passes over a pulley. The pulley, which is mounted in horizontal frictionless bearings, has a radius of R = 0.10 m and a uniform mass of M = 2.0 kg. The two blocks have masses m1 = 4.0 kg and m2 = 7.0 kg, respectively. Assume that the cord does not slip over the pulley.
(a) Show that the rotational inertia of the pulley about its central axis is given by I=1/2mR2.
(b) What is the magnitude of the net torque on the system about the axle of the pulley?
(c) Determine the magnitude of the total
(d) Using parts (a) and (b), calculate the linear acceleration of the two blocks.
