Homework Help: Conservation of Energy and Momentum

  1. Oct 14, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    I know that the velocity of mass at the bottom of the swing is
    V = Sqrt(2gh), but I'm not sure how to get from there to the velocity of A. Is it as simple as Angular momentum of B = Linear Momentum of B?

    What are your answers to parts a and b? (Those are the keys to solving c.)
