A.1 Inertial observer O´ moves at speed v in the negative z-direction with respect to inertial observer O.
Write down the relationship between the sets of coordinates used by the two different observers.
A.2 A rocket moves at speed 4c/5 towards the earth. It fires a missile at a speed of 3c/5 opposite to
its direction of motion as measured on the rocket. With what speed does the missile strike the earth?
A.3 If A = (λ, 1,2,2) is a future-pointing timelike 4-vector, what is the maximum information you know about λ.
