Two boxes, connected by a cord, are pulled horizontally on a frictionless surface with an applied force of 40.0 N. Box A has a
mass of 10.0 kg; Box B has a mass of 12.0 kg.
(Hint: you have Fn & Fg for BOTH vertically, you have decide on the horizontal forces.)
a. Draw a free body diagram for box A.
b. Draw a free body diagram for box B.
c. Find the acceleration, a, of the two boxes.
d. Find the tension, FT, in the cord connecting boxes A and B
