Asked by Macy
Superfly, mass of only 1 gram, but capable of flying 840 million km/hr. meets a locomotive with a mass of 20,000 kg, traveling 40 km/hr. Who has the greater momentum?
I know I need to convert mass to kg and covert momentum in Kg-Km/hr. I just don't know how. Please help.

I would convert 20,000 km to grams.
2E4kg=2E7grams
momentum locomoative=2E7*40 gKm/hr
momentum fly= 1*8.40E8 gkm/hr
momentum locomotive=8E8 gkm/hr
momentum fly=8.4E8 gkm/hr
2E4kg=2E7grams
momentum locomoative=2E7*40 gKm/hr
momentum fly= 1*8.40E8 gkm/hr
momentum locomotive=8E8 gkm/hr
momentum fly=8.4E8 gkm/hr
