Consider a circular-motion problem in which tension not only must provide the proper
radial acceleration but also must balance gravity As we shall see, it can do both. A
tetherball is attached to a swivel in the ceiling by a light cord of length L, as measured
from the ceiling to the center of the tetherball When the ball is hit by a paddle, it
swings in a horizontal circle with constant speed o and the cord makes a constant
angle B with the vertical direction. The ball goes through one revolution in time T.
Assuming that T, mass m, and length L of the rope are known, derive algebrald
expressions for the tension Fr in the cord and the angle B
