Frames k and k' are inertial frames. Frame k' is moving at a velocity of magnitude v realtive to frame k in the direction of the x-axis. there are rigid rods in each frame oriented along the direction of the relative velocity. someone in frame k measures the ros that is stationary in k as having length L1 and the rod stationary in frame k' having a length L'2. What are the lengths of the rods measured by someone in frame k'?
