Answer:
An 8000 kg engine pulls a train of 5 wagons, each of 2000 kg, along a horizontal track. If the engine exerts a force of 40000 N and the track offers a friction force of 5000 N, then calculate the net accelerating force and the acceleration of the train. Hence, Net accelerating force =35000N & acceleration =1. 944ms−2
