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 = 8.9 N. Here A has a mass m = 11.0 kq and B has a mass m = 7.0 kg. The contact force between the two boxes is F. The coefficient of kinetic friction between the boxes and the floor is 0.04. (Assume F, acts in the +x direction.) MA (a) What is the magnitude (in m/s2) of the acceleration of the two boxes? m/s² ma (b) What is the force exerted on mg by m? In other words what is the magnitude (in N) of the contact force F_? Additional Materials (c) If Alex were to push from the other side on the 7.0-kg box, what would the new magnitude (in N) of F. be? N Reading Tutorial THER
