- TL;DR Summary
- Practical issue when staying close to train tracks. Can/Should you do it? What if the Hanoi train was travelling at 100 km/h?
Assume that a 100m long (probably irrelevant) train travelling at 30m/s, with a mass of 100.000 Kg passes next to a man/woman of 100 Kg standing still at 1 m away from the track. Since air is massively displaced by the train, creating like a small vacuum/low pressure area next to its surface, I reckon a certain pull may be applied to anything the train passes by, so in this case a person. My question is very simple: this pull can be quantified by a force. Is this force enough to pull the person under the train? What if the distance was 50 cm?
