1. A pancake body rotates about a fixed origin. Relative to that origin, a point A at A = az on the object has instantaneous velocity UA = voy. At the same instant, a point B at TB = ay has instantaneous velocity UB=-voz. (a) What is the angular rotation vector at that instant? (b) What is the velocity of point C at the location c = (+2)? 2. Find the angular momentum vector (magnitude and direction) of the point C in Problem 1 with respect to point B, assuming the point C has a mass m.
