A horizontal vinyl record of radius 0.0862 m rotates freely about a vertical axis through its center with an angular speed of 4.82 rad/s. The rotational inertia of the record about its axis of rotation is 3.29 x 10-4 kg·m2. A wad of wet putty of mass 43.6 g drops vertically onto the record from above and sticks to the edge of the record. What is the angular speed of the record immediately after the putty sticks to it?
