Confusion regarding Inelastic Collisions contradicting my book
Suppose two bodies $A$ and $B$ with equal mass are kept at a distance. $A$ starts moving towards $B$ at a constant velocity, they hit, and I assume that it is a PERFECTLY INELASTIC collision here.

Relative velocity during a collision
I quote Resonance Kota module on Mechanics(Vol.1):
The collision is just avoided if relative velocity becomes zero just at the moment the two cars meet each other.
I don't understand why should it ...
