I am not sure how to setup this problem. I posted it earlier and "BOB PURSELY" responded we are happy to critique your thinking. I have know idea how to solve this problem or even where to start. Please help!!!

A tetherball leans against the smooth, frictionless post to which it is attached. The string is attached to the ball such that a line along the string passes through the center of the ball. The string is 1.30 long and the ball has a radius of 0.170 with mass 0.440 .

What is the tension in the rope?
What is the force the pole exerts on the ball?
