A solid, thin disk has a moment of inertia of 3.00 x10-2 kg.m2 and spins freely on a frictionless axis at 25.0 rev/min. Suppose then a 0.300-kg ball of putty is dropped vertically onto the turntable and sticks at a point 0.100 m from the center. What is the new rate of rotation of the system? [Hint: Treat the putty as a point mass and calculate final moment of inertia.]
