A car of mass 1200 kg tows a trailer of mass 400 kg along a straight horizontal road, using a light rigid tow-bar.
The engine of the car provides a constant driving force of 3000 N. A constant resistance of 500 N acts on the car and a constant resistance of 300 N acts on the trailer.
Find the acceleration of the car and trailer.
Find the tension in the tow-bar.
