@TheSimpliFire Indeed I have!
@TheSimpliFire I couldn't solve it using momentum, because the solution to the collision needs to involve energy conversation as well.
@Nick It's drawn out simply because you don't understand the basics necessary to understand the long line.
If you are not familiar with set theory, specifically well-orderings and ordinals, as well as topology, specifically point set topology, it is not possible to understand the long line.
And, practically speaking, the long line is not useful. So no point bothering about it. =)
