if OP makes 4 revolutions in one second, the angular velocity in radians per second is?

Explanation

Angular velocity `=frac{text { Distance }}{text { Time }}` `=frac{4 text { revolutions }}{1 text { second }}`



`=frac{4 times 2 pi}{1}`



( `because 1` revolution `=2 pi` radians)


`=8 pi` radians per second
