I haven't practiced archery, nor am I particularly well versed in physics, but I imagine what would usually happen after firing a stick of wood at the usual forces one would do so to kill a thing, it would end up rendered in an unusable condition if not outright destroyed. In fact, I'm more certain it'd be easier to retrieve and reuse successfully fired arrows.
Again, not someone who has experience with launching arrows at things, or someone with command over the arcane numbers governing how the universe works. So take that with a grain of salt.
Now we're helping someone do their physics homework!
It honestly depends on how the arrow lands and what it lands AGAINST. If it's embedded several inches in a wall, it's probably not going to be easily retrievable unless the wall was made of hay or drywall or something similarly soft and pliable. If it's embedded several inches into a living creature, it's
designed to break off, so as to keep the wound open. (Hunting arrows are brutal things.)
If it bounces onto the ground or falls short or wedges into a tree, it should be easy enough to retrieve.
Of course, then you get the sport arrows with fiberglass shafts and no broad head, those won't break nearly as easily but they also need much better precision (and/or luck) to get them to be lethal, since you basically have to directly skewer an organ or major artery.
There's also aluminum and carbon-shafted arrows, but those are generally not going to be something you can find easily in a post-apocalyptic zombie hellscape. (Citation Needed)
