An object is rotating with an angular momentum 4.00 kg m2/s while being acted on by a constant torque 3.00 Nm. What is the angular speed of precession of the angular velocity of the object?
A.1.33 rad/s.
B.0.750 rad/s.
C.12.0 rad/s.
D.zero.
E.It depends on the moment of inertia of the object.

Divide the torque by the angular acceleration. T/L. 4.00 kg m^2/s over 3.00 Nm. A Nm is the same as kg m^2/s^2 so this is the way the units work out correctly to rad/s.
