Question

Two Federation spaceships are traveling at 0.95c, one speeding directly toward the planet Vulcan and one speeding directly away from the planet Vulcan. At one instant, both spaceships happen to be the same distance from Vulcan and they fire a laser at Vulcan. Mr Spock is standing on Vulcan. According to Mr Spock which laser pulse reaches Vulcan first? The light from the spaceship moving toward Vulcan arrives first. The light from the spaceship moving away from Vulcan arrives first. The light from the two ships arrives at the same time. The observer has no way to determine which light reaches Vulcan first.
