An observer moving at a speed of 0.995c relative to a rod (see figure below) measures its length to be x = 2.20 m and sees its length to be oriented at 0 = 33.0° with respect to its direction of motion. 8 Motion of observer (a) What is the proper length of the rod? m (b) What is the orientation angle in a reference frame moving with the rod?
