# Calculate value of the force and the tension in the coupling between the car and caravan in the following case:   A car of mass 1000 kg tows a caravan of mass 800 kg and the two have an acceleration of  2 m/s^2 when an external force acts between the wheels of the car and the road. A car of mass 1000 kg tows a caravan of mass 800 kg and the two have an acceleration of  2 m/s^2. The acceleration is the result of the force between the wheels of the car and the road.

The total mass that is being accelerated due to the force is...

A car of mass 1000 kg tows a caravan of mass 800 kg and the two have an acceleration of  2 m/s^2. The acceleration is the result of the force between the wheels of the car and the road.

The total mass that is being accelerated due to the force is (1000 + 800) = 1800 kg. The acceleration is of 2 m/s^2. The force required for this is 1800*2 = 3600 N.

The coupling between the car and the caravan with which the caravan is being pulled has a tension of 800*2 = 1600 N
