3D Motion/Precession/Stability of a rolling coin

  1. Oct 25, 2009 #1
    1. The problem statement, all variables and given/known data

    See the attached picture for the questions and information. This is actually due today and I haven't gotten all the answers - but it would be good to know how to do everything for when final exams come around. I particularly find (c), (d), (f), and (g) the most difficult.

    2. Relevant equations

    [tex]\dot{\psi}[/tex] = Precession rate
    [tex]\dot{\theta}[/tex] = Nutation rate
    [tex]p[/tex] = Spin

    Angular momentum:

    Forced Precession:
