A 800kg car pushes a 1900kg 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 5000N. Rolling friction can be neglected.
Part A: What is the magnitude of the force of the car on the truck? Express your answer to two significant figures and include the appropriate units.
Part B: What is the magnitude of the force of the truck on the car? Express your answer to two significant figures and include the appropriate units.
