On vacation, your 1400-kg car pulls a 520-kg trailer away from a stoplight with an acceleration of 2.00 m/s2 .

A: What is the net force exerted by the car on the trailer?
Assume that the positive x axis is directed toward the direction of motion.

F = N

What force does the trailer exert on the car?
Assume that the positive x axis is directed toward the direction of motion.

F = N

PART C
What is the net force acting on the car?
Assume that the positive x axis is directed toward the direction of motion.
I FOUND THIS ANSWER F= 200 N

2 answers

m a = 520*2 = 1040 N

third law ---> -1040 N

net force on car = car mass * car a
= 1400 * 2 = 2800 N

the tires exert 1040 N more on the road to accelerate the trailer, but that is not what you asked :)
