A coin is tossed into the air. It is observed to spin at the rate of 600 rpm about an axis GC perpendicular to the coin and to process about the vertical direction GD. Knowing that GC forms an angle  15° with GD.), determine ( a)the angle that the angular velocity ω of the coin forms with GD.(b) the rate of precession of the coin about CD.
