It is a head-on collision, and the acceleration of the jack is found to be 25 m s−2 north. What is the acceleration of the bowl? I've calculated the answer to be 13 ms ^ -2 north; why does my textbook say south instead?

and the acceleration of the bowl is south because it is decelerating in the north direction.
