Two blocks, A and B, of masses 1kg and 3 kg respectively, are placed on a horizontal smooth surface as shown below. A horizontal constant force of 12 N is applied to block A so that the two blocks move to the right with uniform acceleration. What is the magnitude of the contact force between A and B ?

✔ 最佳答案
The acceleration of the system.F=ma
12=(1+3)a
a=3ms-2
The contact force between A and B equal the force acting on B by A.
FA>B=3(3)
F=9N
