Chapter 3, Problem 3.7P
A surveyor measures the distance across a straight river by the following method (Fig. P3.7). Starting directly across from a tree on the opposite bank, she walks d = 100 m along the riverbank to establish a baseline. Then she sights across to the tree. The angle from her baseline to the tree is θ = 35.0°. How wide is the river?

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.
