40 metric tons is a mildly overloaded tractor-trailer! I've seen many
coal train cars that specify loaded weights in the 100 metric ton range.
If idiot "B" were to stand in the path of one of our local coal trains,
the he would be attempting to defy a mass more in the 10000 metric ton
range.
If you want to see *really* fun engineering physics, you should go
to a coal fired power plant. Our local plant has a forklift-type
mechanism which grabs one of these 100 (+/-) metric ton coal cars
off the tracks, lifts it up over the plant input hopper, dumps the
coal into the hopper, and replaces the car on the tracks. Impressive.
