How do I do this Physics Force Problem?

Sep 28, 2007 by Phil | Posted in Physics

Famer attaches 25kg bale of hay to one end of rope passing over a frictionless pulley connected to beam in hay barn. Another farmer pulls down on opposite end of rope with force of 277 N. Ignoring mass of rope, what will be the magnitude and direction of the bale's acceleration if the gravatational force acting on it is 245 N?
