Alex is asked to move two boxes of books in contact with each other and resting on a frictionless floor. He decides to move them at the same time by pushing on box A with a horizontal pushing force F, = (+8.20î )N. Here A has a mass ma = 13.3 kg and has a mass ma = 7.00 kg. The contact force between the two boxes is Fr and N denotes the normal force. F. m. (a) What is the magnitude of the acceleration of the two boxes? m/s² (b) What is the magnitude of the force F, exerted on m, by m,? N (c) If Alex were to push with the same magnitude of force |F from the other side on the 7.00 kg box, what would be the magnitude of the force F, exerted on m, by ma? (Assume the force F, on the left side is no longer present.) N
