Q. A horizontal vinyl record of mass 0.10kg and radius 0.10 m rotates freely about a vertical axis through its center with a rotational speed of 5.10 rad/s. The rotational inertia of the record about its axis of rotation is 5.0 x10-4 kg•m2. A wad of wet putty of mass 0.03 kg drops vertically onto the record from above and sticks to the edge of record. What is the rotational speed of the record immediately after the putty sticks to it?
