Question

A train pulls some carriages. The train exerts a force of 40,000N and frictional force act in the opposite direction with a force of 35, 000N. The total mass of the train and carriages is 200,000kg. What is the acceleration of the train?​

Explanation:

So lets see,

The acceleration of the train

We know that, F = mass x acceleration

Or, 35000 N = (mass of engine + mass of 5 wagons) X a

Or, 35000N=(8000kg+10000kg)×a

Or, 35000N=18000kg×a

⇒a=35000N/18000kg=1.944ms−2
