Scalar component and the vector projection of F

  1. Jan 9, 2009 #1
    A force F of 6 units acts in the direction 30 degrees west of north. An object is
    constrained to move north-westerly, that is, 45 degrees west of north.
    (a) Sketch the force vector roughly to scale on a set of axes that has the positive y
    axis pointing north, and write F using exact values, either in the form (x; y) or
    else in the form xi + yj.
    (b) Write a vector in the direction of the given movement of the object.
    (c) Without using trigonometric functions, ¯find both the scalar component and the
    vector projection of F in the direction of movement of the object. Write both
    answers as exact values, not decimal approximations.
