  Hadronic phase and its dynamics in relativistic heavy-ion collisions are
topics of immense discussion. In this respect, resonances can play an important
role in determining the characteristics of the hadronic phase as they have
sufficiently small lifetimes, which may be comparable to the hadronic phase
lifetime. The resonances produced at the QCD phase boundary undergo
re-scattering and regeneration processes within the hadronic medium. We use a
1+1D second-order viscous hydrodynamics for the evolution of hadronic medium to
govern $K^*(892)^0$ kinematics. Hydrodynamics breaks down at the Knudsen number
($Kn$) limit: $Kn>1$, where the mean free path becomes sufficiently large
compared to the system size and the particle yield gets preserved. Further, net
yields of $K^*(892)^0$ \& $K$ are obtained at the kinetic freeze-out boundary,
.i.e. $Kn>1$. In the current study, we predict hadronic phase lifetime and then
the ratio of $K^*(892)^0/K$ is obtained, which qualitatively agrees with the
experimental data as a function of the final state multiplicity.
