Two objects of different masses are joined by a light rod.
(a) Is the moment of inertia about the center of mass the minimum or the maximum? Why?
(b) If the two masses are 3.0 kg and 5.0 kg and the length of the rod is 2.0 m, find the moments of inertia of the system about an axis perpendicular to the rod, through the center of the rod and the center of mass.
