Question

Edward travels 150 kilometers due west and then 200 kilometers in a direction 60° north of west. What is his displacement in the westerly direction?
150 kilometers
200 kilometers
250 kilometers
350 kilometers

Answer 1

so is it 150 kilometers..? I am absolutely horrible at physics

Answer 2

so we know its 150 to the west + however far the 2nd vector goes to the west

Answer 3

that should give you your total displacement in the west direction.
