A 1200 Kg car pulls an 820 Kg trailer over a rough road. The force of friction acting on the trailer is 650 N.(backwards). Calculate the force that .... ....the car exerts on the trailer if
a). The trailer is moving at a constant velocity of 30 Km/h.
b). The trailer is moving forward at 60 Km/h and starts accelerating 1.2 m/s^2 (backwards).

We can use Newton's second law of motion for this.
F = Force that car exerts on trailer
F1 = friction force = 650N
For the first part since it is running with constant velocity there is no...
