Homework Help: Rod moves in x-y plane

  1. Dec 12, 2008 #1
    1. The problem statement, all variables and given/known data

    A rod AB of length 2m moves in horizontal x-y plane. at any instant end A of rod is at origin and has velocity v_a =2i +v_y j. the other end B at the same instant is moving with velocity v_b = 2i +6j. the rod makes an angle of 30 degrees with the x-axis at this instant. find:

    1. the magnitude of angular velocity of the rod.

    2. value of v_y .

    3. the component of velocity of cetre of mass in the direction perpendicular to the rod at given instant.
