Homework Statement
Alex is asked to move two boxes of books in contact with each other and resting on a rough floor. He decides to move them at the same time by pushing on box A with a horizontal pushing force FP = 9.3 N. Here A has a mass mA = 10.6 kg and B has a mass mB = 7.0 kg. The contact force between the two boxes is Fc
The coefficient of kinetic friction between the boxes and the floor is 0.04. (Assume fp acts in the +x direction)
a) What is the force exerted on mB by mA? In other words what is the magnitude of the contact force
