Answer:

36255 Kg.

Step-by-step explanation:

From the question given above, the following data were obtained:

Momentum = 1450200 Kgm/s

Velocity = 40 m/s

Mass =?

Momentum is simply defined as the product of mass and velocity. Mathematically, it is expressed as:

Momentum = mass × velocity

With the above formula, we can obtain the mass of the train as follow:

Momentum = 1450200 Kgm/s

Velocity = 40 m/s

Mass =?

Momentum = mass × velocity

1450200 = mass × 40

Divide both side by 40

Mass = 1450200 / 40

Mass = 36255 Kg

Thus the mass of the train is 36255 Kg
