A 1260 -kgkg car is pushing an out-of-gear 2200 -kgkg 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 4460 NN . The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 765 NN , 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 magnitude FConTFConT 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 F⃗ ConTF→ConT points, is the positive x direction.
Express your answer in newtons to three significant figures.
