A rocket ship of proper length \(l_0\) travels at constant velocity \(v \) relative to a frame S. The nose of the ship \((A')\) passes the point \(A \) in S at \(t=t'=0\), and at this instant a light signal is sent from \(A'\) to \(B'\).

Here's my figure |dw:1444376673186:dw| the time \[t' = \frac{ l_0 }{ c }\] for the sginal to reach the tail B' of the ship. My question is, at what time \(t_1\), as measured in S, does the signal reach the tail \(B'\) of the ship.

Yeah, I sort of tried all of this already, I'm not quite sure at this point haha

But its still fairly simple all you need to do is contact the length and then use classical physics to figure out the time taken..

\[\tau = \tau_0 \gamma\] I did try that oh..I think it's because this is the first question where I have the frames the other way around so my algebra must be wrong..

\[l =\frac{ l_0 }{ \gamma }*\]

Figured it out, thanks anyways @Mashy :)
