To determine the net force acting on the truck and trailer, we need to compare the forward and backward forces.
- The force the truck exerts forward: 2,750 newtons.
- The force the trailer exerts backward: 2,790 newtons.
Net force can be calculated as:
Net force = Force forward - Force backward
Net force = 2,750 N - 2,790 N
Net force = -40 N
A negative net force indicates that the force is acting in the opposite direction of the forward force.
This means that the truck and trailer will experience a net force of 40 newtons backward.
So, the correct answer is:
C. The truck and trailer will experience a net force of 40 newtons backward.
