Help With Angular Acceleration

  1. Oct 2, 2008 #1
    1. The problem statement, all variables and given/known data
    A meter stick is hinged at its lower end and allowed to fall from a vertical position. With what angular speed does it hit the table?

    2. Relevant equations
    V = rW (Not sure?)

    3. The attempt at a solution
    I have no clue where to even start with this problem, given the small amount of given data.

    Obviously a meter stick is 1m long. But this doesn't get me very far. I know that gravity is also acting on the object so that would have to be included somewhere in my calculation. Basically I'm completely lost on this one.

    Thanks for your help / guidance.
