1. Firecrackers and rockets: Suppose a rocket pilot sets off two firecrackers, the second exactly 10 days after the first (according to the pilot). Now suppose that according to an observer on Earth, the rocket is moving at a constant speed v and the two firecracker-explosions are spatially separated by Ax = 2· 1014m, i.e. that the rocket travels a distance Ar between the explosions. How much time passed on Earth between these explosions?
