26. A top is spinning at 28.6 rev/s about an axis making an angle of 34.0° with the vertical.
Its mass is 492 g and its rotational inertia is 5.12 x 10-4 kgm2. The center of mass is 3.88 cm from the pivot point.
The spin is clockwise as seen from above.
Find the magnitude (in rev/s) and direction of the angular velocity of precession.
