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

A frieght train has a mass of 1.5x10^7 kg. The wheels of the locomotive push back on the tracks with a constant net force of 7.5X10^5N, so the tracks push forward on the locomotive with a force of equal magnitude. (ignore aerodynamics and friction) how long would it take to increase the speed of the train from rest to 80km/h?

2. Relevant equations

3. The attempt at a solution

So far I was able to calculate the acceleration:

a=F/m

a=7.5*10^5/1.5*10^7

a=5*10^12m/s^2

am I going in the right direction and how would I proceed?
