A1200-kg car pushes a 2100-kg truck that has a dead battery to the right. when the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500 n.

what is the magnitude fct of the force that the car exerts on the truck? use the coordinate system shown in parts c and d, where the positive y direction is upward, and the positive x direction is to the right, the direction in which f⃗ ct points. express your answer in newtons to two significant figures.
