A 1260kg car pushes a 2180kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4510N. Take the friction between the truck's tires and the ground to be 450N. What is the magnitude of the force the car applies to the truck? What is the magnitude of the force the truck applies to the car?
