A gyroscope with rotational inertia 6.4 10-3 kg·m2 is precessing in a horizontal plane at 0.46 rad/s under the influence of a 0.31 N·m torque caused by a force pointing vertically downward. How fast is the gyroscope spinning on its axis?

Sorry, rotational inertia I = 6.4 * 10^-3 kg*m^2.

I really am stuck on this, can't figure out how to use angular momentum/torque relations to connect the dots and be able to solve for what they're asking ;\.

Hey this is what I did:

T=Ia
a= T/I

then divide a/precessing velocity
