A horizontal vinyl record of mass 0.124 kg and radius 0.101 m rotates freely about a vertical axis through its center with an angular speed of 6.00 rad/s and a rotational inertia of 4.32 x 10-4kg·m2. Putty of mass 0.0437 kg drops vertically onto the record from above and sticks to the edge of the record. What is the angular speed of the record immediately afterwards?
