A hоrizоntаl vinyl recоrd of mаss 0.0522 kg аnd radius 0.0932 m rotates freely about a vertical axis through its center with an angular speed of 5.71 rad/s and a rotational inertia of 2.02 x 10-4 kg·m2. Putty of mass 0.0189 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?
