A thin uniform cylindrical turntable of ra- dius 2.9 m and mass 17 kg rotates in a hori- zontal plane with an initial angular speed of 7.5 rad/s. The turntable bearing is friction- less. A clump of clay of mass 5.4 kg is dropped onto the turntable and sticks at a point 1.8 m from the point of rotation.
Find the angular speed of the clay and turntable.
Answer in units of rad/s.
