physics

A locomotive that has a mass of 6.4 x 105 kg is used to pull 2 railway cars. Railway car 1 has a mass of 5.0 x 105 kg, is attached to railway car to that has a mass of 3.6 x 105 kg by a locking mechanism. A railway engineer tests the mechanism and estimates that it can only withstand 2.0 x 105 N of force. Determine the maximum acceleration of the train that does not break the locking mechanism. Explain your reasoning. Assume that friction is negligible.
