(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A handball of mass 0.10 kg, traveling horizontally at 30 m/s, strikes a wall and rebounds at 24 m/s. What is the change in the momentum of the ball?

2. Relevant equations

change in momentum = mv2 - mv1

3. The attempt at a solution

Do you take 24 as negative or positive? If you take it as neative you get -2.4-3=-5.4 if you take it as positive you get 2.4-3= -.60

both answers given in the problem are either positive 5.4 or positive 6.0. Thanks for your help
