A turntable has a moment of inertia of 0.030 kg-m2 and spins freely on a frictionless bearing at 25 rev/min. A 300 gram ball of putty is dropped vertically onto the turntable and sticks at a point 0.10 meter from the center.
A. Determine the new rate of rotation of the system?
B. Determine the kinetic energy of this system before and after the putty is dropped onto the turntable?
