Question

Figure 10.1 shows a student swinging a ball in a circle about his head. Show that the rope cannot be exactly horizontal. (Hint: Take the rope’s tension force T to be at an angle below the horizontal, and examine the components of T. Use a diagram to illustrate.)

Figure 10.1 Centripetal acceleration. An object in uni-
form circular motion must have a centripetal acceleration
with a magnitude of a = ²/r directed toward the center
of the circular path. In the case of swinging a ball on a
rope around one's head, the centripetal force F = ma is
supplied by the person and transmitted through the rope.
