Which do you think the correct answer was wrong
Help plis:(

36255 Kg.

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

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

seeing the graph would
