In an attempt to escape from a deserted island, a castaway builds a raft and sets sail for the sea. The wind changes a lot during the day and flies along the following straight lines: 2.60 km and 45.0 ° north of west, then 4.80 km and 60.0 ° south of east, then 1.60 km and 5.00 ° east of north, and finally 2.70 km and 13.0 ° north of the east. Use the analytical method to find the resulting vector of all its displacement vectors. What is its magnitude and direction?
