Impulse question!

  1. Jul 19, 2004 #1
    ok, i get this question that says:
    "An object of mass 3.0 kg is moving in the neg. x direction with a speed of 2 m/s. it is acted upon by a force with an impulse of 24 N s. What is the final momentum and the final velocity after that impulse has acted on the object? so i did

    P(initial) = mv
    P = 3 x -2 = 6
    J = (mv)final - (mv)initial
    24 = (mv)final - (-6)
    18 = mv
    18 = (3.0)v
    v = 6 m/s

    so 18 is the final momentum and 6 is the final velocity?
