A car of mass 800 kg is using a chain to tow a trailer of mass 200 kg along a straight horizontal road. The engine of the car produces a driving force of 1.5kN.
Find the acceleration of the system and the tension in the chain assuming that there is no resistance to motion.

Find the acceleration of the system and the tension in the chain assuming that there is no resistance to motion.
Draw a labelled force diagram and resolve horizontally, using f=ma, for the car and caravan. You should be able to cancel T between the two equations to find the acceleration. Finding the tension is then simple.
If you're still having trouble with it, let me know and i'll post a solution.

Find the acceleration of the system and the tension in the chain assuming that there is no resistance to motion.
For the car:
1500 - T = 800a
---> T = 1500 - 800a
For the trailer:
T = 200a
Equating the expressions for T gives:
---> 1500 - 800a = 200a
---> 1500 = 1000a
---> Acceleration (System) = 1.50 ms^-2
Tension (Chain) = 200(1.50) = 300 N
