Question #67057, Physics / Mechanics | Relativity

Edward travels 150 kilometers due west and then 200 kilometers in a direction $60{}^{\circ}$ north of west. What is his displacement in the westerly direction?

Solution:

Displacement in west direction: $d = d_{1} + d_{2}\cos (60{}^{\circ}) = 150 + 200*\frac{1}{2} = 150 + 100 + 250m$

Answer: 250 meters
