Three identical 6.0-kg cubes are placed on a horizontal frictionless surface in contact with one another. The cubes are lined up from left to right and a force is applied to the left side of the left cube causing all three cubes to accelerate to the right at 3.0 m/s2 . What is the magnitude of the force exerted on the right cube by the middle cube in this case?
a. 12 N
c. 24 N
b. 18 N
d. none of the above
