The cord is used to swing a 15-kg stone in a circular path of radius 1.0 m over an icy surface. What cord tension is necessary as a function of angular frequency? What is the maximum angular frequency such that the cord will not break?

Aside from this question, the book doesn't mention the term "angular frequency" for another 200 pages. And it describes it as something that doesn't even relate to this problem. And it calls it ω which is what the current chapter uses for angular velocity.

I believe this problem wants me to solve either:

What is the max angular speed without breaking the cord, and what tension is necessary as a function of angular speed

(ie: Tension(ω) = .....)

or

What is the maximum amount of rotations per second will the stone can make without breaking the cord, and what tension is necessary as a function of rotations per second

(ie: Tension(rps) = ....)

I'm not asking for help in doing the problem. I just want to know what they're asking

Also, what does the icy surface have to do with it? It does not give the mass of the person swining the stone, so I can't compute a barycenter. I guess in writing the formula for the Tension function, the person's mass could be introduced as a variable. But that's far beyond the scope of this chapter. There is nothing in the chapter on circular motion that talks about an origin that is not fixed. And there's no guarantee that the person isn't standing on rock surrounded by ice in which case the stone would still fulfill the question's requirements of being swung over an icy surface.

thanks...
