This problem involves connected objects and friction.
Newton's second law:
A 1260 -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 4440 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?
What is the acceleration aT of the truck?
Express your answer in meters per second squared to three significant figures.
