Hi, Is it possible to predict the “angular consequences” of an elastic collision? Let’s say we have two rectangular objects, A and B. Their original angular velocities and linear velocities, as well as mass and moment of inertia, are all known. Is it than possible to predict their angular velocities after they hit, knowing the collision-point? If so then how, because I can only figure out one equation, where both unknown angular velocities are stated: I[A] * w[A](before) + I * w(before) = I[A] * w[A](after) + I * w(after) where as w(after) and w[A](after) are unknown... any ideas?
