A woman with mass 50 kg is standing on the rim of a large disk that is rotating at 0.80 rev/s about an axis through its center. The disk has mass 270 kg and radius 4.0 m. Calculate the magnitude of the total angular momentum of the woman–disk system. (Assume that you can treat the woman as a point.) Express your answer to two significant figures and include the appropriate units.
A disk of radius 2.05 m rotates about its axis. Points on the disk\'s rim undergo tangential acceleration of magnitude 2.71 m/s2. At a particular time the rim has a tangential speed of 1.51 m/s.
