A train of 8000 tons at a velocity of 30 km/h roughly has the kinetic energy of 66.39 kg TNT.
I don’t think your units make sense — kinetic energy has units of energy, but “kg TNT per second” is power (about 4MW). (I think just remove the “every second” and it’s correct?)
Edit: parent edited comment.
You’re right, but “every second” was meant more as a display of the energy in the train, like a large explosion “every second”. Is that very wrong?
Hmmm, I’m not sure I understand…
A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.
But that’s just my interpretation.
It seems to be a lot, how does it compare to an artillery shell? The tank doesn’t look like it fared too badly.
Artillery shell with 1 kg of TNT has explosion energy of about 1 kg of TNT
Do they actually use TNT as the explosive though? I thought TNT was just the igniter for something more powerful like C4 or something.
