I think it has 11 but i don't really know for sure.Correct me if i'm wrong.
The angular speed can be solve using the formula:
w = v / r
where w is the angular speed
v is the linear velocity
r is the radius of the object
w = ( 5 m / s ) / ( 5 cm ) ( 1 m / 100 cm )
w = 100 per second
Viscosity is a kiwi that flows very slowly
