Jo 43. A horižontal rod of proper length L moves with a uniform speed v> 0 along the X-axis of a coordinate frame. A ground observer measures the position coordinates of its two ends at two different times with time difference At> 0 The observer finds that the difference between the two coordinates is L. Calculate At in terms of L, v and the speed of light c. If measured correctly, what would have been the length of the rod in the ground frame? O
