Question

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.

Answer 1

Answer:

a) net accelerating force = 40000- 5000 = 35000

b) acceleration

40000 - 5000 = mass × acceleration

35000 = 18000× acceleration

acceleration = 1.9 m\ s²
