A turntable has a moment of intertie of 3.00 x 10-2 kg•m2 and spins freely on a frictionless bearing at 25.0 rev/min. A 0.300 kilogram ball of putty is dropped vertically on the turntable and sticks at a point 0.100 meter from the center. Find by what factor the angular momentum of system change after the putty is dropped onto the turntable?
