I saw a freight train cruising by today and thought "The momentum of that thing must be mind-blowing". I only have high school physics and thus couldn't calculate the momentum including many external forces. Did some quick research and was wondering what the momentum of an 80 car freight train traveling 40km/h would be? The average car being approximately 110.2 tons or 100,000kg
I came up with:
p=mv
p= (100,000*80)*(11.11...)
p= 88,888,889 kgm/s
Thats a lot of momentum but with friction, drag etc what would it actually be?
