Just a glimpse at why MIT is hard. The first problem on my 2.003 PSET. If you have any idea how to or have calculated omega, let me know how please. I know the velocity of the center of mass and the moment of inertia but can't figure out how much of the impulse is transfered into rotational energy. Actually, if you know the rotational energy that's just as useful, so let me know about that as well. Click the image to make it bigger.
