1.62 On a training flight, a Figure P1.62
student pilot flies from Lincoln,
Nebraska, to Clarinda, Iowa, next
to St. Joseph, Missouri, and then to
Manhattan, Kansas (Fig. P1.62). The
directions are shown relative to north:
0° is north, 90° is east, 180° is south,
and 270° is west. Use the method of
components to find (a) the distance
she has to fly from Manhattan to get
back to Lincoln, and (b) the direction
(relative to north) she must fly to get
there. Illustrate your solutions with a
vector diagram.
