A turntable has a moment of inertia of 3.00 × 10^-2 kg•m2 and spins freely on a frictionless bearing at 25.0 rev/min. A 0.600-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.100 m from the center. By what factor does the angular momentum of the system change after the putty is dropped onto the turntable?

a. 1.22
c. 0.820
b. 1.00 (no change)
d. 1.20
