two boxes are connected by a
cord running over a pulley. The coefficient of kinetic friction
between box A and the table is 0.31. Ignore the mass of the cord
and the pulley friction. In this case we can assume that the force
applied to one end of the cord will have the same magnitude at the
other end. Find a) acceleration, b) the Tension force FT
in the cord. Assume box A is twice the mass of box B = 2.31_kg.
