Two equal masses(1 and 2) are connected by an ideal rope across a pulley. This system is on a larger block A; 1 is on top of A, while 2 is hanging off the side, and the pulley rests on the corner of A. The question is what is the minimal acceleration of A such that masses 1 and 2 remain stationary. No variables given, please HELP!
