A group of construction workers are building a house and want to lower an excess bundle of bricks that has a mass of 205 kg from the second story window to the ground. They tie one end of a rope to the bundle of bricks, loop it through a pulley and tie the other end to a 102.5 kg toolbox. If the coefficient of kinetic friction between the toolbox and the floor is 0.440, what is the acceleration of the bundle of bricks?
