Chapter 2, Problem 2.10CYU

Check Your Understanding Verify that vector v $\text{<mover accent="true"> <mi> V </mi> <mo> ^ </mo> </mover>}$ obtained in Example 2.14 is indeed a unit vector by computing its magnitude. If the convoy in Example 2.8 was moving across a desert flatland—that is, it the third component of its velocity was zero—what is the unit vector of its direction of motion? Which geographic direction does it represent?
