  • 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?1.     Two boxes A and B are connected by a lightweight cord (disregardthe mass of the cord).
