Chapter 5.3, Problem 18E
Pursuit curve In another naval exercise a destroyer S1 pursues a submerged submarine S2. Suppose that S1 at (9, 0) on the x-axis detects S2 at (0, 0) and that S2 simultaneously detects S1. The captain of the destroyer S1 assumes that the submarine will take immediate evasive action and conjectures that its likely new course is the straight line indicated in Figure 5.3.10. When S1 is at (3, 0), it changes from its straight-line course toward the origin to a pursuit curve C. Assume that the speed of the destroyer is, at all times, a constant 30 mi/h and that the submarine’s speed is a constant 15 mi/h.
- (a) Explain why the captain waits until S1 reaches (3, 0) before ordering a course change to C.
- (b) Using polar coordinates, find an equation r = f (θ) for the curve C.
- (c) Let T denote the time, measured from the initial detection, at which the destroyer intercepts the submarine. Find an upper bound for T.

The urban heat island phenomenon hasbeen observed in Tokyo. The average temperature was13.5C in 1915, and since then has risen 0.032C per year. Assuming that temperature T (in C) is linearly related to time t (in years) and that T=0 corresponds to 1915, express T in terms of t.
An endurance training runner begins at point A and races to point B, then switches and races again to point A, then switches and races again to point B. The position for the athlete at time (t) is given by:
s(t)=t^3-6t^2+9t-2
a) On which intervals is the velocity positive? In which direction is the runner running during these intervals?
b) On which intervals is the velocity negative? In which direction is the runner running during these time intervals?
c) At which point is velocity zero? What is the runner’s movement at these points?
