A child's top is spinning with its axis making an angle of 13.6 with respect to the vertical. Its center of gravity is 13.6 cm from its tip, its mass is 304 grams, and its moment of inertia is 16868.4 g cm^2. It is observed to precess 0.731 times per second. The acceleration of gravity is 9.8 m/s^2. How fast is it spinning? Answer in units of rad/s.

A space station is coast me ted in the shape of a hollow ring of mass 5.00 104 kg.
