Question

A simple gyroscope consists of a wheel (R= 0.75 m,I= 0.9 MR2) rotating on a horizontal shaft. If the shaft is balanced on a pivot 0.50 m from the wheel, and the wheel rotates at 500 rev/min, what is the precession frequency of the wheel?
A) 1.9 x 10-2rad/s
B) 2.9 x 10-2rad/s
C) 0.19 rad/s
D) 0.28 rad/s
E) cannot be calculated without knowing the mass of the wheel
