A horizontal vinyl record of mass 0.0855 kg and radius 0.101 m rotates freely about a vertical axis through its center with an angular speed of 4.18 rad/s and a rotational inertia of 2.64 x 10-4 kg·m2. Putty of mass 0.0253 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?

Expert Solution
Step 1

Given:-

The horizontal vinyl record of mass  M= 0.0855 kg 

The radius r = 0.101 m 

The angular speed of ωi= 4.18 rad/sec  

The rotational inertia I = 2.64 x 10-4 kg m2

 Putty of mass m = 0.0253 kg drops vertically onto the record from above and sticks to the edge of the record

find:-

.What is the angular speed of the record immediately afterward?
