Module 24: Lorentz Transformation: Examples  Problem 3
Imagine a team of observers (Team Red) are riding a red broomstick, and zip by Earth at speed $v$. Assume the origins of Team Earth and Team Red cross at $t = t^\prime=0$ (that is, $(t=0, x=0) = (t^\prime= 0, x^\prime= 0)$). Imagine that a member of Team Red located at their origin has stolen a top secret file. So, you jump on your new superbroomstick, and chase after Team Red at speed $V$ which is larger than $v$. You leave Earth at time $t = t_1$. (To distinguish the various $\gamma$ factors, write $\gamma[w]= \frac{1}{\sqrt{1w^2}} $ for any $w$ expressed in units with $c = 1$).

Question 5 of 5
5. Question
According to your watch (which read $t_1$ when you left Earth), what time is it when you catch up with the outlaw? (Don't concern yourself with the effects of acceleration. Instead, if you are bothered, imagine that the question is more precise: Another observer moving past Earth with speed $V$, passes the origin of the Earth's frame at time $t_1$ on their own clock (and on Team Earth's clock). What time will that observer say it is when they catch up with the outlaw who is at the origin of Team Red?)
CorrectIncorrect
