and try these:
Rotational problems
Your are 3 m from the center of a carousel. The carousel turns half a turn, i.e. pi radians. How far did you move?
The carousel makes one complete rotation in 10 seconds, how far did you move in those ten seconds?
How fast were you going in m/s? This is your tangential velocity.
How many radians did it turn in those ten seconds? [ answer is 2 pi] How many radians did it turn in one second?
What was your angular speed (its called omega) in radians / second?
Was your tangential speed (m/s) equal to omega times 3 m?
