Homework Help: Special Relativity Problem (1.364, Irodov)

  1. Mar 9, 2009 #1
    1. The problem statement, all variables and given/known data
    The rod AB oriented parallel to the x' axis of the reference frame K' moves in this frame with a velocity v' along it's y' axis. In its turn, the frame K' moves with a velocity V relative to the frame K as shown in Figure. Find the angle (theta) between the rod and the x-axis in the frame K.


    2. Relevant equations
    Lorentz Transformation:
    x' = (x-Vt)/(1-(V/c)2)1/2; y = y' (Doubtful in this case)
    vx' = vx - V/(1-vxV/c2);
    vy' = vy (1-(V/c)2)1/2/(1-vxV/c2).

    3. The attempt at a solution
    As far as I know that the rod AB in frame K should not be tilted at all, I mean it must remain horizontal if x and x' axis of K and K' frames coincide, or am I wrong? So, my only problem is that - "Is it possible for rod to be tilted in frame K?"

    In image, by fault there are two v' written for the velocity of rod, so don't be confused.

    And on emore thing the problem is 1.364 from Problems in General Physics - I. E. Irodov.
