Imagine a long brick in outer space. You apply a force tangential to the center of mass. The brick accelerates in a transitional and angular fashion. There are no constraints or fixed axis. How would I calculate the translational and angular acceleration? I would like to run some simulations with Mathematica. I understand rotational problems with fixed axis and translation problems if the force vector passes through the center of mass. This problem is different. One force will cause rotation and the center of mass to move. I would appreciate any kind of help. Maybe I just don't know the correct google search terms to figure this out.
