Homework Help: Vector Directions

  1. Sep 4, 2004 #1
    Am I interpreting this question correctly?

    So, does that mean:

    Vector A=8 at 45 degrees
    Vector B=8 at 180 degrees

    or

    Vector A=8 at 45 degrees
    Vector B=8 at 225 degrees

    I know how to do the problem, it's just interpreting the book's wording on angles.

    Thanks

    A at 45 degrees and B at 180 degrees. Saying vector B points in the -x direction is the same as saying vector B makes an angle of 180 degrees with the +ve x axis.

    225 degrees would be opposite to A's direction not in "the -x direction. ... "
