Thanks for your help. I understand how to derive the moment of inertia of a cylinder, however given that the question wants the angle between the angular velocity and L, a cross product would need to be used. As far as I know, L = Iw is not a cross product so one would have to use L = r x mv in...

Hi BvU :) Thanks for the prompt response. Here is the diagram that accompanies the exact text. https://drive.google.com/file/d/0B55WioybuKMBR25NaDU3LVItMVk/view?usp=sharing

Homework Statement A uniform cylinder of mass M and radius R can be rotated about a perpendicular axle through its centre. A particle of mass m is attached to the cylinder's rim. The system is rotated with angular velocity w about the axle, which is held in a fixed direction during the motion...
