Learning Goal: A 1290 -kg car is pushing an out-of-gear 2200 -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 4580 N. The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 755 N, including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck?

Question
Transcribed Image Text: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, ñ, and FG are, respectively, friction, normal force, and gravity; subscripts C and T stand for "acting on car" and "acting on truck"; FConT is the force exerted on the truck by
the car; and FTonc is the force exerted on the car by the truck. Note that the force vectors are not drawn in scale.
