A turntable has a moment of inertia of 3.0 ´ 10-2 kg×m2 and spins freely on a frictionless bearing at 25 rev/min. A 0.30-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.10 m from the center. By what factor does the kinetic energy of the system change after the putty is dropped onto the turntable? (show your work and all formulas used)
