Imagine that you are traveling in a spaceship that passes by Earth at a velocity of 0.87c (Lorentz factor = 2), and you fire an escape pod from your spaceship pointed straight up (in the y or z direction, perpendicular to the spaceship’s direction of travel). If the escape pod has a perpendicular speed of 0.6c with respect to your ship, what is the perpendicular speed of the escape pod from the perspective of a person on Earth?

In the twin paradox example done in lecture, just before Alice arrives at the star (before she slows down), she observes Bob’s clock back where he is located. (In other words, she has a photo taken of his clock and her corresponding clock at that location, her clock being part of her lattice of clocks.) Compared to her clock, does she observe Bob’s clock to be behind, ahead, or the same time as hers?

Consider two identical light clocks, designed as explained in lecture. Bob has one, and Alice takes the other on her spaceship and flies by Bob at speed V. Bob observes Alice’s clock. What is the relationship between a certain amount of elapsed time on Bob’s clock and the corresponding elapsed time on Alice’s clock, as observed by Bob (where γ represents the Lorentz factor)?
