A `8000kg` engine pulls a train of `5 wagons`, each of `2000kg`, along a horizontal track. If the engine exerts a force of `40000N` and the track offers a frictional force of `5000N`, then calculate:  (a) the net accelerating force, (b) the acceleration of the train, and  (c ) the force of wagon 1 on wagon 2.
