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. Find the new rate of rotation of the system?
in rev/min
b. Find the kinetic energy of this system before and after the putty is dropped onto the turntable?
