If I am not totally wrong..ehh many numbers and late at night :-)
The earth would have to spin with about 1 rotation pr. 100min
or : 0,011 RPM
this would be a circumf. speed of 24 000 km/h
Now it spins with : 1 rot. pr. 1 440 min.
and a cricumf. speed of : 264,5 km/h
: : Just a thought: centrifugal force is sort of an anti-gravity force. Picture the earth spinning fast enough to fling us off the surface.
: Now this is a question I have always wanted to ask-how fast
: must the earth spin for 0 gee at the surface? How long would
: a day be?
