Finding magnitude of displacement vector

  1. Oct 9, 2008 #1
    [solved] finding magnitude of displacement vector

    Silas crawls 1.5 meters due East then crawls 3.2 meters due South. Find the magnitude of the net displacement vector. Make sure you do the following in your answer:

    * include correct units
    * make your answer correct within 0.02
    * make your answer positive (because magnitudes are always considered positive)
    * put your answer in a form like one of these:
    o #.## m
    o #.## meters

    The question is worth one point, and there is a half point penalty for each incorrect submission.
    i got a resultant vector of 3.534m but that was using pythagorean theorem (1.5squared+3.2squared)= 12.49---> square root 12.49=3.53 but i dont know what it means by magnitude...am i doing it right?

    Magnitude just means size. It is exactly what you calculated.
