A 30,000 kg locomotive is moving at a velocity of 10 m/s east. What is the locomotive's momentum?

You spelled chemistry wrong that the only answer your getting.

To find the momentum of an object, you need to multiply its mass by its velocity. In this case, the mass of the locomotive is 30,000 kg and its velocity is 10 m/s east.

The momentum can be calculated using the formula:

Momentum = Mass × Velocity

Substitute the given values into the formula:

Momentum = 30,000 kg × 10 m/s

Now perform the multiplication:

Momentum = 300,000 kg·m/s

Therefore, the momentum of the locomotive is 300,000 kg·m/s.
