I'm not seeing any difficulty here. The trajectory exeption does not apply as per description (A1 is still a potential kicker), pass interference rules apply even after a kick if the forward pass is legal and PSK does not come into play, so it's gonna be team A's ball, 1/10 at B-40, take your pick on the lateral positioning of the ball. Game clock on the snap, though, as it was a legal kick down.
