Angular Speed versus Linear Speed
Hello Brndo:
If you're thinking of how fast a point on the surface of the earth is moving through space as the planet rotates, then you're confusing angular speed with linear speed.
Check out a few of these links from Google to learn about the difference.
Angular speed states how many radians are swept out by a central angle per fixed unit of time. So, it has more to do with how fast the planet is rotating, not how fast points on the surface are moving.
To answer your exercise, consider the answers to the following two questions.
For a point on the surface of the earth, how many radians are swept out by the central angle in a single rotation of the planet?
How much time does this take?
Cheers,
~ Mark
