Homework Help: Help with resultant velocity

  1. Sep 24, 2006 #1
    can someone help me with this question:
    Calculate the resultant velocity of a pair if 100 km/h velocities at right angles to each other

    i dont even understand what the question is asking me

    Velocities are represented with vectors, so use http://www.codesampler.com/d3dbook/chapter_02/chapter_02_files/image012.jpg" [Broken]. However, for different vector orientations, you get different resultant velocities.

    k thank you, that helped a lil...would this be the right answer then:

    Since both velocities are equal we have to times one of the sides by the square root of 2. Which means that the reluctant velocity is 141.4.
