Chapter 2, Problem 44R

To determine

To explain: the reason why hurricane’s speed is not enough information to be able to warn people to evacuate.

Explanation of Solution

Introduction:

To figure out how far an object is positioned or how fast it is traveling, one needs a reference point from which to calculate it. Any physical calculation is begun from a point of reference. Measurement is object status with respect to some other related parameter.

The exact direction of the motion of the hurricane can’t be predicted. Just base on the assumption of motion, warming people to evacuate is not possible.

Conclusion:

Hence, one can’t predict the exact direction of the hurricane's motion.
