Two boxes A and B are connected by a lightweight cord (disregard the mass of the cord). Box A has a mass of 5.0 kg and rests on a horizontal table. The coefficient of kinetic friction between the box and the table is 0.20. Box B has a mass of 2.0 kg and hangs over the table via a frictionless, massless pulley. Assume the cord does not stretch (i.e., the boxes have the same acceleration).

What is the acceleration of the boxes?

What is the tension in the cord that connects the boxes?
