Two boxes are connected by a weightless cord

running over a very light frictionless pulley as shown

in the figure. Box A, of mass 8.0 kg, is initially at

rest on the top of the table. The coefficient of kinetic

friction between box A and the table is 0.10. Box B

has a mass of 15.0 kg, and the system begins to move

just after it is released.

(a) Draw the free-body diagrams for each of the boxes,

identifying all of the forces acting on each one.

(b) Calculate the acceleration of each box.

(c) What is the tension in the cord?
