This physics video tutorial explains how to solve the tetherball problem by calculating the tension force in the rope. You need to draw a free body diagram for this uniform circular motion problem. The horizontal component of the tension force is equivalent to the centripetal force. The weight force is supported by the vertical component of the tension force.
