I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.
To be clear, the thing that hit 700 km/h (a different unit from mph) in under 2 seconds was essentially a sled. Not a full train car.
Japanese trains go up to 320 km/h on current lines.
Anyway, the camera movements in the video kinda look sped up too.
Here is the same video without being sped up
Here is a future Japanese bullet train doing 500 km/h if they build out the maglev line.
