Velocity Vectors

  1. Jan 29, 2008 #1
    The velocity vector V1 has a magnitude of 3m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 2m/s. The sum of the two is V3, so that V3 = V1+V2

    Which is True ?

    A) The magnitude of V3 can be 0
    B) The magnitude of V3 can be 6m/s
    C) The magnitude of V3 can be 5m/s
    D) The x-component of V3 can be -1m/s
    E) The magnitude of V3 can be -4m/s
    F) The magnitude of V3 can be 3m/s

    C and D, but i know it's wrong... i just don't understand velocity vectors.

    take a look here if you don't know how to add two vectors.
