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.

    I know that some generator turbines go ~3600 rpm

    If my (admittedly super rusty) math is right if we assume a radius of 1 meter which would mean a circumference of ~6.28 meters. In that case the tips of the turbines would be moving:

    6.28 * 3600 =22,608 meters per minute.

    Please feel free to rip up my math as I’m going on little sleep at the moment.
