A model of a `CO_(2)` molecule is made of two spheres, each of mass `m_(1)`, representing oxygen atoms and a sphere of mass `m_(2)` in between, representing the carbon atom. The spheres are interconnected by springs of force constant k. Such a system can vibrate freely in two the ways shown by arrows. Find the frequencies in the two cases.
