Use the link above to solve the problem.
Part 1) What is the magnitude of the angular momentum of the 3.1 kg, 4.5-cm-diameter rotating disk in the figure ?
Part 2) What is it's direction?
For the first part, I think I need to use the equation L=Iw, but I got it wrong when I did, so I may have used the wrong numbers. If I am using the wrong equation, please tell me.
