[問題] 題目看不太懂
An armada of spaceship that is 1.00ly long(in its rest frame)
moves with speed 0.800c relative to a ground station in frame
S. A messenger travels from the rear of the armada to the front
with a speed of 0.950c relative to S.
How long does the trip take as measured
(a) in the messenger's rest frame?
題目給的兩個速度不是都是相對於S嗎?
可是我看詳解他是用相對速度的那個公式去算@@
不太懂
我看中文版他把messenger翻譯成旅客? 翻錯了吧?
messenger應該是在spaceship外面吧
幫我解釋一下 謝謝
