A blob of putty of mass m = 75.0 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 = 1.70E-2 kg•m2 that is rotating freely with angular speed 3.77 rad/s about its vertical fixed-symmetry axis. Find the post collision angular speed of the turntable-putty system?
