Homework Help: Addng vectors

  1. Oct 17, 2007 #1
    Here is the problem i need help with.

    I run up a down escalator at a speed of 2 m/s while the escalator is moving at a rate of 0.75 m/s. What is the resultant velocity?

    Of course, I do not need help getting the resultant velocity. I just need help drawing the vector diagram that can help me get the resultant velocity. Pretty dumb on my part, but yes any assistance would be most grateful.

    One is running in the opposite (up) direction of the down escalator.

    Draw a vector of magnitude 2 m/s up the escalator, and another vector of magnitude 0.75 m/s down the escalator.

    What is the sum?

    1.25 m/s would be the resultant velocity, And i get how to draw the diagram now, thanks for the help.
