Consider Alice’s spaceship with the paintball apparatus that shoots two paintballs toward clocks at opposite ends of her ship, each with speed S relative to the apparatus (similar to the video lecture). Assume that Alice has properly synchronized her clocks, that her spaceship is moving with speed V to the right (in the positive x direction) relative to Bob, that S is greater than V, and that S and V are much less than the speed of light. True or false: In Bob’s frame of reference, the two paintballs will hit Alice’s clocks simultaneously.

Consider a train with three cars, moving to the right past Alice, who is on a train station platform. The front of the first car reaches Alice at time t = 0. In Alice’s frame of reference, which set of world lines represents the world lines of the three cars? (Let a world line represent the front of the car.)
