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?

I know that the velocity of mass at the bottom of the swing is
V = Sqrt(2gh),
That would be true if the pivot were fixed.

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