Solve the all parts of given question:

Question: 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, mass less pulley. Assume the cord does not stretch (i.e., the boxes have the same acceleration).

Part A: What is the acceleration of the boxes?

Part B: What is the tension in the cord that connects the boxes?

I need help to find the tension in the cord that connects the boxes.
