  In the present work, we carry out the study of scattering solitons for the
anti-kink/kink and kink/anti-kink configurations. Furthermore, we can observe
the same effects as those described by D. Bazeia et al.. We apply the
collective coordinate approximation method to describe both scattering
configurations and verify that just as happens in the polynomial models
$\phi^4$ and $\phi^6$, the method has its limitations regarding the initial
scattering speeds. In such a way that, for certain initial speeds, the solution
of collective coordinates agrees with the fullsimulation, and for other speeds,
there is a discrepancy in the solutions obtained by these two methods. We also
noticed that, considering the hybrid model, the null-vector problem persists
for both configurations, and when trying to fix it, a singularity is created in
moduli-space as well as in $\phi^4$.
