A 3 kg disk of radius 0.25m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center of mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft(the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia of the shaft is negligible, a) What is the angular speed of the disk-ball combination, b)...
