A 1220-kg car pulls a 390-kg trailer. The car exerts a horizontal force of 3.6 × 10³ N against the ground in order to accelerate.

What force does the car exert on the trailer? Assume an effective friction coefficient of 0.19 for the trailer.

(Express your answer to two significant figures and include the appropriate units.)
