Krystelle jogs 200m west and then 60m north. Find the magnitude and direction of the resultant displacement.?

Question

Clue:

200m west and 60m north

Answer 1

displacment is the hypothenuse of the distance of 200 and 60m, so use pythagoras theorem.

displacement = sqrt (60^2+200^2) = 208m northwest

Answer 2

Another clue: Pythagoras discovered (or copied from some Egyptian scholars) that a^2+b^2=c^2.

Also note that the tangens of the angle is the ratio 200/60
