Components and Vectors and Lengths, Oh My!

  1. Sep 10, 2009 #1
    Hey guys! I am back for a second time. (Woo) More Awesome Physics underway!

    1. The problem statement, all variables and given/known data

    The components of a vector V are often written (Vx, Vy, Vz). What are the components and length of a vector which is the sum of the two vectors, V1 and V2, whose components are (3.4, 1.0, 15.0) and (5.1, -4.6, -1.0)?



    2. Relevant equations

    (Vx)=8.5
    (Vy)=-3.6
    (Vz)=14


    3. The attempt at a solution
    To my understanding it should be (Vx)² + (Vy)² + (Vz)² = √Length

    But my Program say nay to such an answer...Is there somthing I missed?

    Ugh I fail, a Negative Being Squared is Positive... Void all that, I suck. : (
