...holds a bicycle wheel.? The wheel has a rotational velocity of 5 rev/s about a vertical axis. The rotational inertia of the wheel is 2 kg*m^2 about its center and the rotational inertiaof the student and wheel and platform about the rotational axis of the platform is 6 kg*m^2.

A. What are the magnitude and direction of the initial angular momentum of the system.

B. If the student flips the axis of the wheel, reversing the direction of its angular-momentum vector, what is the rational velocity of the student and the stool about their axis after the wheel is flipped?

I know this is long, but I can't seem to figure out what equations to use. Any help would be greatly appreciated!
Sorry, that first sentence should say at rest, not at res.
