Homework Help: Vectors, magitude, scalar components

  1. Jan 28, 2009 #1
    1. The problem statement, all variables and given/known data

    the displacement vector A has scalr omponents of Ax= 80.0 m and Ay= 60.0 m. the displacement vector B has a scalr component Bx= 60.0 m and a magnitude of B=75.0m. The displacement vecto C has a magnitude of C= 100.0 m and is directed at an angle of 36.9 degrees above the + x axis. Two of these vectors are equal. determine which two, and support your choice with a calculation.

    2. Relevant equations

    3. The attempt at a solution
    vector A= 100m
    By= 45m
    vector A= vector C

    So vector A and vector C have the same magnitude. Can you show they're both 36.9 degrees above the x-axis.
