Homework Help: Components of vectors

  1. Jun 14, 2010 #1
    1. The problem statement, all variables and given/known data

    Vector A is 3.28 m long and points along the x axis. Vector B is 190.6 cm long and points at +25° to the positive x axis
    (a) What are the components of Vector A?
    (b) What are the components of Vector B?
    (c) What is the resultant of these two vectors in terms of components?
    (d) What is the resultant of these two vectors in terms of magnitude and direction
    2. Relevant equations
    I think we are trying to find Ax, Ay, Bx, and By

    3. The attempt at a solution
    I am not certain on where to begin here, any help would be good, thanks!

    Try drawing each vector in its own coordinate axis first with repsect to the origin. The magnitude of vectors will always be the norm or hypentenuse of a right triangle. Since you are given an angle with respect to the horizontal axis and a magnitude, you can use trig to break it apart into its components. Try that and see if you can't make sense of (c) & (d) from that relationship.
