.Consider a very light rod rotating about its center. At each end of the rod is a mass. It is rotating at angular velocity 10 rad/s. A mechanism now moves the masses towards the center of the rod so they sit half way between the center of rotation and the end of the rod. Assuming no external torque is acting on the system, what is the angular velocity once the masses are moved to their new location? A) 5 rad/s B) 20 rad/s C) 2.5 rad/s D) 40 rad/s
