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?

We will be happy to critique your thinking.

the tension T=ma, since the only acceleration is that due to gravity.. a=g (9.8m/s^2) so T=0.442*9.8
