Reviewing for exam-how would i find the displacement of two vectors?

  1. Oct 7, 2007 #1
    what if i'm given the length of two vectors and asked to find displacement? how would i find the direction?

    i'm reviewing for an exam and looking over some example problems in a text i have. there are no solutions. would i find the x and y components? rx=rcos(theta) and ry=rsin(theta)?

    You can't.
    Were you given the angle as well as the length?

    here's the problem:

    a plane goes 29 meters north, and then changes direction to go east at 35 degrees for 50 meters.
