Finding the force vector of an object with angular velocity

[1101]

So let's say i have two cubes. If one of them slams into the other (assuming it isn't moving at all) then the force vector is just going to be the direction the first cube was moving in correct? But say that this first cube also had angular velocity on some arbitrary axis, in other words it's rotating. How exactly would I find the force vector in this case? I don't know the torque of this collision but I do know the displacement vector. I also know the masses, locations, angular/linear speeds, and other general information (i realize this is pretty ambiguous) about the cubes. I'm trying to make a physics engine for a game and I don't have a huge background in physics or anything.

hi 1101!

i don't know what you mean by the force vector …

force doesn't really come into it …

you need conservation of momentum and also conservation of angular momentum
