In Exercises 65-68, write the definite integral for finding the indicated arc length or surface area. Then use the integration capabilities of a graphing utility to approximate the arc length or surface area. (You will learn how to evaluate this type of integral in Section 8.8.)
Length of Pursuit: A fleeing object leaves the origin and moves up the y-axis (see figure). At the same time, a pursuer leaves the point (1,0) and always moves toward the fleeing object. The pursuer’s speed is twice that of the fleeing object. The equation of the path is modeled by .
How far has the fleeing object traveled when it is caught? Show that the pursuer has traveled twice as far.
