Suppose we have a whirling string $($spinning around its axis$)$ of length $9$ meters, tension $8$ Newtons, and linear density $0\mathrm{.}09$ kilograms per meter.

Suppose it is popped out completely $($it never crosses the axis, only at the endpoints$).$ How fast is it spinning $($angular velocity$)$ in terms of radians per second?

Angular velocity: $$ help $($numbers$).$
