7. [-/3 Points] DETAILS OSCOLPHYS1 5.P.012.TUTORIAL WA. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 F, 8.5 N. Here A has a mass m (Assume F, acts in the +x direction.) 10.2 kg and has a mass me = 7.0 kg. The contact force between the two boxes is F The coefficient of kinetic friction between the boxes and the floor as 0.04. m₂ Mu (a) What is the magnitude (in m/s) of the acceleration of the two boxes? m/s² (b) What is the force exerted on my by m? In other words what is the magnitude (in N) of the contact force F (c) If Alex were to push from the other side on the 7.0-kg box, what would the new magnitude (in N) of Febe?
