Two objects of equal masses A and B are connected to a system of pulleys as shown in the figure uploaded. The pulleys are assumed to be smooth. Calculate the acceleration of A.
The Attempt at a Solution
I can't figure out the second equation for b becaus I think it is attached to the pulley and will remain stationary. However, in the proposed solution, there's an equation for the movement of b too. How is that possible?[/B]
