A small blob of putty of mass m = 80.0 gram falls from the ceiling and lands on the outer rim of a turntable of radius R =15.0 centimeter and moment of inertia I = 1.80 E-2kg•m2 that is rotating freely with angular speed 3.77 rad/s about its vertical fixed-symmetry axis. Compute what is the post collision angular speed of the turntable-putty system?
After several turns, the blob flies off the edge of the turntable. Find the angular speed of the turntable after the blob's departure?
