Vector addition problem needs help

  1. Sep 12, 2008 #1
    The velocity vector V1 has a magnitude of 4m/s and is directed along the +x-axis. The velocity vector V2 has a magnitude of 3m/s. The sum of the two is V3, so that V3 = V1+V2
    (For each statement select T-True, or F-False; If the first is True and the rest F, enter TFFFFF).

    A) The magnitude of V3 can be 7m/s
    B) The x-component of V3 can be 0m/s
    C) The magnitude of V3 can be -4m/s
    D) The magnitude of V3 can be 0
    E) The magnitude of V3 can be 8m/s
    F) The magnitude of V3 can be 3m/s

    i hate these tyes of problems can someone please help me out

    Tell us what you have tried so far. The math is only addition and subtraction, so your problem begins by finding out what a vector is. You got a text book?
