Chapter 3, Problem 41

(choose chapter or problem)

Linear vs. Angular Speed A wheel of radius 30 centimeters revolves at a rate of 10 revolutions per second. A dot is painted at a point P on the rim of the wheel (see figure).

(a) Find \(d x / d t\) as a function of \(/theta\)

(b) Use a graphing utility to graph the function in part (a).

(c) When is the absolute value of the rate of change x of greatest? When is it least?

(d) Find \(d x / d t\) when \(\theta=30^{\circ} \text { and } \theta=60^{\circ}\).
