Question: An engine pulls a train of 20 freight cars, each having a mass of 5.42 x 104 kg with a constant force. The cars move from rest to a speed of 3.97 m/s in 15.1 s on a straight track.

Part A: Ignoring friction, what is the force with which the tenth car pulls the eleventh one (at the middle of the train)?

Please explain how you came to your conclusion to find the force with which the tenth car pulls.
