Homework Equations


I have calculated the kinetic energy and the total moment of inertia. https://www.physicsforums.com/file:///C:/Users/javad/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png [Broken]

The Attempt at a Solution


I really don't know how to solve the problem. Hope someone can lead me on the right track.

Was there some initial rotational velocity or means to set the wheel rotating?

The image link you've placed in the relevant equations section is broken. It likely points to a location that is not publicly accessible. Note that the relevant equations section is for listing equations, typically from your course notes or text book repertoire of equations, that you feel might be useful or applicable to solving problems of this type. It's not meant to hold part of the solution itself, or statements of what you've done.

You'll have to show an attempt at solution before help can be offered (your thread risks deletion for lack of effort). At least describe what you have tried or what approaches you've considered.
