Well, I'm writing some code for a physics simulation. I have two 3-dimensional rigid (non-deformable) bodies moving around in a 3-D environment, and occasionally, they collide with each other. To account for the general case, I have to assume they both have initial translational and rotational...
Let's say there are two rigid bodies in space, each has an initial translational velocity as well as an initial angular velocity. Eventually, these two bodies collide. The collision causes the translational and angular velocities of both bodies to change, resulting in 4 unknowns (each unknown...
