gyroscope consists of a rotating uniform disk with a 60-cm radius, suitably mounted at one end of a 15-cm-long axle (of negligible mass) so that the gyroscope can spin and precess freely. Its spin rate is 1540-rev/min. What is the rate of precession if the axle is supported at the other end and is horizontal?

I got .0035353535
but I do not know the units
did I do this correctly?
