Alex Is Asked To Move Two Boxes Of Books In Contact With Each Other And Resting On A Rough Floor He Decides To Move The 1 (16.66 KiB) Viewed 51 times

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 = 8.5 N. Here A has a mass mA = 10.2 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 magnitude (in m/s2) of the acceleration of the two boxes?
m/s2
(b)
What is the force exerted on mB by mA? In other words what is the magnitude (in N) of the contact force
FC?
N
(c)
If Alex were to push from the other side on the 7.0-kg box, what would the new magnitude (in N) of
FC
be?
N
