In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45 .0 ° north of west, then 4.70 km and 60 .0 ° south of east, then 130 km and 25 .0 ° of west, then 5.10 km due east, then 1.70 km and 5 .00 ° east of north, then 7.20 km and 55 .0 ° south of west, and finally 2.80 km and 10 .0 ° north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?

A plane leaves the airport in Galisteo and flies 170 km at 68.0° east of north; then it changes direction to fly 230 km at 36.0° south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to this plane? (With precise solution please)
A. 351km with a direction of south
B. 351km with a direction of 11.8 degrees south of west
C. 351km with a direction of 11.8 degrees south of east
D. 351km with a direction of east
In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind
shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km
and 45° north of west, then 4.70 km and 60° south of east, then 1.70 km and 5° east of north,
and finally 7.20 km and 55° south of west. Use the analytical method to find the magnitude
and direction of the resultant vectors.
