Answer to Question #136617 in Physics for Sovereign T. Wleh

Question

from the northeast side of Bushrod Island proceed on a course of 135 (magnetic) for 1450 m; then alter course to 180 and proceed for 620 m; then alter course to 285 and proceed for 1190 m; finally alter course to 0 and proceed 730 m to reach West Point harbor. What is the displacement vector from Bushrod Island to the harbor? Solve this problem graphically, by making an accurate, large diagram showing the successive displacement vectors.

Answer 1

Draw the diagram:

As we see, the total displacement is is around 1000 m.
