Chapter 5, Problem 34PE
A 20.0-m tall hollow aluminum flagpole is equivalent in stiffness to a solid cylinder 4.00 cm in diameter. A strong wind bends the pole much as a horizontal force of 900 N exerted at the top would. How far to the side does the top of the pole flex?

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.

- 3.19 • Win the Prize. In a carnival booth, you can win a stuffed gi- raffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal dis- tance of 2.1 m from this point (Fig. E3.19). If you toss the coin with a velocity of 6.4 m/s at an angle of 60° above the horizontal, the coin will land in the dish. Ignore air resistance.
