Problem 2

If the centripetal force on an object in uniform circular motion is increased, what is the effect on (a) the frequency of rotation $f($ with $r$ constant) and (b) $f$ and $r$ when both are free to vary?

Problem 4

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.)
