|| A tetherball leans against the smooth, frictionless post to which it is attached. (See Figure 5.46) The string is attached to the surface of the ball such that a line along the string passes through the center of the ball. The string is 1.40 m long and the ball has a radius of 0.110 m with mass 0.270 kg. (a) Make a free-body diagram of the ball. (b) What is the tension in the rope? (c) What is the force the pole exerts on the ball?
