[SOLVED] Topic: Newton's third law

A 2.0 kg bowl strikes the stationary ‘jack’, which has a mass of 1.0 kg, during a game of bowls. 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?

How did you get 13 m s^-2 ?

he may have rounded off from 12.5.
and the acceleration of the bowl is south because it is decelerating in the north direction.
