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

A 0.70 kg ball is moving horizontally with speed of 9.6 m/s when it strikes a vertical wall. The ball rebounds with speed of 1.3 m/s. What is the magnitude of the change in linear momentum of the ball?

2. Relevant equations

Dp = mv(f) - mv(i)

3. The attempt at a solution

I solved for mv(f) and mv(i). Solved for Dp which I got -5.81 which is wrong.
