Question
the truck are both accelerating along the x direction and at the same rate, so
Learning Goal:
To practice Problem-Solving Strategy 7.1 for
interacting-objects problems.
ac = aT = Og.
A 1200 -kg car is pushing an out-of-gear 2160 -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 765 N
including the "friction" of turning the truck's drivetrain.
What is the magnitude of the force the car applies to
the truck?
Solve
Part C
What is the magnitude FConT of the force that the car exerts on the truck? Use the coordinate system shown in Part B, where
upward is the positive y direction and to the right, the direction FConT points, is the positive x direction.
Express your answer in newtons to three significant figures.
