A particle moves with velocity v' in the x'y' plane of the rocket frame in a direction that makes an angle phi' with the x'-axis. Discover the angle phi that the velocity vector of this particle makes with the x-axis of the laboratory frame. (Hint: Transform space and time displacements rather than velocities.) Why does this angle differ from that found in Exercise L-6 on transformations of angles? Contrast the two results when the relative velocity among the rocket and laboratory frames is very great.
