Of a rolling disc? Or a rolling sphere? Its different for every geometric object. The formula is [tex]L = I \omega[/tex]
And for future reference, anything to do with angular dynamics equation can be easily found by using various substiution:
mass = moment of inertia
v = omega
Force = Torque
Distance = Theta
acceleration = angular acceleration
So F = ma, in rotational dynamics is Torque = Moment of inertia * Angular Acceleration.
Just replace all the terms.
