Homework Help: 3 Questions I just can't seem to figure out

  1. Feb 18, 2008 #1
    1. The problem statement, all variables and given/known data
    1. A displacement vector has a magnitude of 810m and points at an angle of 18 degrees above the positive x axis, What are the x and y scalar components of this vector?

    2. A displacement vector is 23 km in length and directed 65 degrees south of east
    What are the components of this vector (East=x South =y)

    3. Four members of the Main Street bicycle club meet at a certain intersection on Main Street. The member then start from the same location, but travel in different direction. A short time later, displacement vectors for the four members are:
    A=2.0km east B=5.2km north C= 4.9km west D=3.0kmsouth
    What is the resultant displacement R for all the members of the bicycle club
    r=a+b+c+d



    2. Relevant equations



    3. The attempt at a solution
    No clue where to start

    Well the place to start would be to read up on what is meant by components of a vector. Try looking here, for example.
