Calculate the change in momentum of a 120g pool ball hitting at 9m/s and rebounding at 6m/s. It rebounds at an equal and opposite angle of 45 degrees.

Pi = 9m/s

Pf = 6m/s

angle = 45 degrees

2. Relevant equations

3. The attempt at a solution

I have done all my calcs in the picture below which shows a diagram

I have concluded that the impluse was 10.8166 N, somehow I don't think I have done this right
