A .015 kg coin of diameter .013 m is spinning at 9 rev/s about a vertical diameter at a fixed point on a tabletop. a) If the coin spins about a vertical diameter at 9 rev/s while its center of mass travels in a straight line across the tabletop at .05 m/s, what is the angular momentum of the coin about a point on the line of motion?
b)what is the angular momentum of the coin about a point .1 m from the line of motion?(there are two answers to this question)
