(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What speed must a 15 metric ton train travel to have a momentum of 700,000 kg(m/s)?

2. Relevant equations

Momentum = mass X velocity

change in momentum = mass(Finalvelocity - initialvelocity)

3. The attempt at a solution

I though you did it like this...

15 metric tons= 15,000 kg

so 700,000=15,000V

V=46.6 m/s
