Homework Help: Magnitude and direction of the resultant.

  1. Sep 15, 2008 #1

    i have 2 arrows/vector. One going down 13m and one going up 3m. it ask what is the magnitude and direction.

    Direction should be south and north. But how do i find the magnitude? and what is that?

    is it:

    -13 + 3 = -10m?

    That's pretty much correct, but the magnitude would be the absolute value of what you wrote.

    Does the problem say the vectors are "up" and "down", or does it say "north" and "south"? The direction will be one of those.
