A large wooden turntable of radius 2 m and total mass 120 kg is set to rotation from rest about a vertical axis through its center, with angular velocity 3.0 rad-s-1 at 4s. A bag of sand of mass 100 kg is dropped vertically onto it, at a point near the outer edge. (a) Calculate the torque applied for the rotation. (b) Find the angular velocity of the turntable after the sandbag is dropped.
