A rotating horizontal disk with a radius of 2 m and a mass of [M] kg has an initial angular velocity of [w0] rad/s. Two objects, each modeled as point masses, are dropped onto the disk’s surface and adhere to it. Object A has a mass of [mA] kg and object B has a mass of [mB] kg. r1 = 1.2 m and r2 = 1.5 m.  Determine the final angular speed of the system. Express your answer in rad/s.
