A 1200-kg car is pushing an out-of-gear 2180-kg truck that has a dead battery.
When the driver steps on the accelerator, the drive wheels of the car push
horizontally against the ground with a force of 4550 N. The rolling friction of the car
can be neglected, but the heavier truck has a rolling friction of 770 N, including the
"friction" of turning the truck's drivetrain. What is the magnitude of the force the car
applies to the truck?
Assuming that the car pushes the truck to the right, which of the following free-body diagrams is the correct diagram for the situation described in this problem? In each case, the diagram on the left
refers to the car, and that on the right to the truck. Dashed lines connect action/reaction pairs. The following notation is used: f, n, and FG are, respectively, friction, normal force, and gravity;
subscripts C and T stand for "acting on car" and "acting on truck"; F ConT is the force exerted on the truck by the car; and F Tonc is the force exerted on the car by the truck. Note that the force
