What speed does the patrol spaceship appear to be traveling according your reference frame? Let frame S be the rest frame of the Earth and frame S’ be your spaceship moving at speed vto the right relative to the Earth. The patrol spaceship is then an object moving at speed uin the S frame. Now, find the speed u’of the patrol spaceship in your S’ frame.
