# impulse momentum help

**1. The problem statement, all variables and given/known data**

**2. Relevant equations**

**3. The attempt at a solution**

I used ∫Fdt = m(vf-vo)

and came up with -.822 m/s for the final velocity…

I have been reworking this problem over and over and cannot come up with a different answer…

Am i wrong in using the impulse momentum theorem?
