Homework Statement
I am having a issue relating part of this question to the Galilean transformation.
Question
Relative to the laboratory, a rod of rest length ##l_0## moves in its own line with velocity u. A particle moves in the same line with equal and opposite velocity . How long dose it take for the particle to pass the rod.
Homework Equations
##v=v'+w##
The Attempt at a Solution

So my issue is relating the velocities to the gaillen transformation. My ans from a) , b) and c) for velocity seen in each ref frame is ##2u##, which has been workout from the right side of the diagram, but my issue is relating to the left side diagrams which are Galilean where ##S## the stationary frame and ##S'## is the moving ref frame.
So more first diagram if I use the gallien equation displayed in the relevant equations then I make the velocity ##-2u## comapred to the middle where I make it ##2u## and for the last I make it ##0## which is obviously not correct. This has always been my issue, when relating to the gaillen transformations, I just can never figure what equations to use for a give situation, but if I do it like have on the left side I have a better understanding.
I was just wondering if someone could advise me on where I seem to go wrong.
