Collision of Two Masses

    2. Relevant Equations

    p = mv

    (v1m1 + v2m2)
    Vf = --------------------
    (m1+m2)



    3. The attempt at a solution

    I got that the total momentum was 9.64 by using p=mv for summing m1, v1 and m2, v2. Then I used inverse trig to try to find the angle, but all the answers I submit are incorrect. I'm not sure what way to go here.

    The momentum is vector, and the momentums sum as vectors.

    All the answers are still positive, so I don't understand what you mean.

    How do you add two vectors?
