Superfly, mass of only 1 gram, but capable of flying at the incredible speed of 840 million km/hr, meets a locomotive with a mass of 20,000 kg, traveling at 40km/hr. Who has the greater momentum?

To determine who has greater momentum between the superfly and the locomotive, we need to calculate the momentum of each object. The momentum of an object is given by the equation:

Momentum = Mass × Velocity

Let's calculate the momentum for each object.

For the superfly:
Mass = 1 gram = 0.001 kg (since 1 kg = 1000 grams)
Velocity = 840 million km/hr = 840,000,000 km/hr

It's important to note that before we can compare the two objects, we need to ensure that the units are consistent. The velocity of the superfly is given in km/hr, while the velocity of the locomotive is given in km/hr as well. Therefore, we don't need to convert anything.

Momentum of the superfly = Mass × Velocity
= 0.001 kg × 840,000,000 km/hr

Now, let's find the momentum of the locomotive:
Mass = 20,000 kg
Velocity = 40 km/hr

Momentum of the locomotive = Mass × Velocity
= 20,000 kg × 40 km/hr

By calculating these values, we can compare the momentum of each object.
