Unformatted text preview: extends d = 19 .1 ft from its base, as shown in the ﬁgure. A sailor on the deck of a ship
sights the top of the lighthouse at an angle of θ = 30 .2 ◦ above the horizontal. If the sailor’s eye
level is h2 = 15 .5 ft above the water, how far is the ship from the rocks?
Problem 10: (a) Rank the vectors in the diagram in order of increasing magnitude. (b) Rank
the vectors in order of increasing value of their x components. (c) Rank the vectors in the above
diagram in order of increasing value of their y components.
Problem 11: The velocity vector V1 has a magnitude of 4 .0 m/s and is directed along the
+x-axis. The velocity vector V2 has a magnitude of 3 .0 m/s. The sum of the two is V3 , so
that V3 = V1 + V2 . Which of the f...
