I have been working on making a 2-dimensional physics simulation on my computer and am having a bit of trouble with collisions. I know that:(adsbygoogle = window.adsbygoogle || []).push({});

-horizontal momentum is conserved

-vertical momentum is conserved

-kinetic energy (both rotation and translational) is conserved (assuming elastic collision)

-angular momentum is conserved

I have also created another equation that determines the angle at which the objects are deflected. That leaves me with 5 equations, but I need to know:

-horizontal velocity after collision (for both objects)

-vertical velocity after collision (for both)

-angular velocity (for both), which leaves me with 6 unknowns.

How else can I relate these variables so that I can solve for them explicitly?
