Coming back to the question, does that mean if the entire cylinder is accelerating/jerking then it would take the time of a wave moving at the speed of sound (in the medium) to cover a light year before the entire rod would come to a halt and until then would continue to accelerate/jerk despite not having a force behind it?
You used the term rod coming to a halt twice now, you probably refer to halting the acceleration.

But let's make it clear to everybody than when the force stops the rod will continue to move, the back will immediately stop to accelerate and eventually the front as well.
