    1. At the onset of the problem we don't know anything about the direction of the angular velocity. What I did in this problem (and other planar rotation problems) is assume a direction of rotation, and let the numbers tell me if I'm right or wrong. In this problem there are no numbers, but if you can see based on the math that the actual direction of the angular velocity of the body will be dependent on the quantities for v and v_a.
