Homework Help: 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

    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?
