I have completed the animation of the elastic collision

and the inelastic one
https://www.geogebra.org/classic/atdrbrse
where, in both cases, I noticed a strange phenomenon.
 
In the inelastic collision, body A with mass m_A=1 exerts a force
F_AB=+v on body B, because it increases its speed from vi_B=-v to
vf_B=0.

In a collision the force is not constant in time. It is initilally
sero and finally sero but if it is always zero there is no collision.
How the force varies duriong the collision depends on details that
are not discussed below. In the special case of zero duration of the
collision the force is infinite.
