## Homework Statement

## The Attempt at a Solution

I'm going to post all that I figured out or tried. Most of it is really just pieces of information that I don't know how to put together.

The frame is accelerating, so I have to apply a pseudo-force of [tex]\frac{3mg}{2}[/tex] on B and C in the leftward direction.

The Center of Mass of the system lies on the midpoint on B and C. I know the distance between the CoM and A.

I tried energy conservation, taking zero potential at BC. That didn't help either.
