I'm trying to calculate the angular momentum of a coin spinning about a vertical diameter about its center of mass. Given is mass, diameter, and angular velocity. I thought it would be [tex]L=\frac{1}{4}MR^2\omega[/tex]. The angular momentum about a point away from the coin I thought would be [tex]L=\frac{1}{4}MR^2\omega + Mh^2\omega[/tex] where [tex]h[/tex] is the distance from the axis containing the diameter of the coin to the point away from the coin. And if the coin's center of mass were moving in a straight line while doing the two above things, then I thought that to each of those would be added [tex]MvR[/tex]. I'm guessing that it is just something simple that I missed in the beginning which propagated the error through the other parts of the problem. Help would be greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});
