Initial momentum = 1.6*5.5 + 2.4*2.5 = 14.8
Final momentum= 1.6*1.9 + 2.4*4.9 = 14.8
Initial momentum=final momentum
And similarly
Initial Kinetic energy = Final Kinetic energy
So collision is elastic.
Hope it clears.

It is perfectly elastic collision as energy is conserved. Final and initial kinetic energies are same !!

In elastic collision kinetic energy and momentum is conserved .
in inelastic collision only momentum is conserved.
Here ,kinetic energy is conserved so it is elestic collision..
Thanks and Regards
