Answer:

1.08 x 10⁷N

Explanation:

Given parameters:

Mass of freight train  = 270700kg

Acceleration = 40m/s²

Unknown:

Force acting on the train = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

So;

        Force  = 270700 x 40   = 1.08 x 10⁷N
