In this case the animation agrees with both of us because there is no direction change. Try it with a direction change like my example and compare to your momentum law.

the flash is not correct because if you set both A and B to 1000 kg and set the velocity of A to 1 m/s
you end up with more kinetic energy than you started with.

I think you mistyped something there. Have another go. Make sure e=1 to conserve kinetic energy.
