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.
You’re moving at about 700 m/s while sitting in your couch, according to Earth’s rotation. So if the plane goes west at max speed, it would be 1400 m/s faster than going east.
