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. 18 N
b. none of the above
c. 12 N
d. 24 N
Homework Answers
Here, the force on the right cube is given by
F = ma
Here the mass is identical and acceleration is same for all
F = 6*3
F = 18 N

Three masses are in a line, in contact, on a frictionless surface with the smallest mass 3 kg to the left, the intermediate mass 8 kg in the middle and the greatest mass 13 kg mass on the right. A 33 N force is applied horizontaly in the right direction to the smallest mass. Calculate the contact force (in N) between the smallest and the middle mass.
