2. Drawing free-body diagrams for objects in motion.
The following questions refer to a system of three identical
bricks, stacked as shown in Fig. 1, being pushed across a table
horizontally at a constant speed. Each brick has mass m. Call
the stack of two bricks System A, and the single brick on the
right System B. There is a frictional force with coefficient ?.
a) Compare the net force on System A to the net force on
System B. How did you come to this conclusion?
b) Draw separate free-body diagrams for System A and System B. Label each force by
identifying the type of force and the object exerting the force (for example, Ffriction on A).
Fig

c) Is the magnitude FAB , the force exerted on System B by System A greater than, less than, or
equal to the magnitude FBA , the force exerted on System A by System B? Why?
d) The forces FAB and FBA are often called action-reaction forces or force pairs. Newton
