Homework Help: Momentum check

  1. Apr 28, 2010 #1
    1. The problem statement, all variables and given/known data

    The diagram shows a body, A, of mass 2.00 kg resting in a frictionless, horizontal gulley in which it is constrained to move. It is acted upon by the force shown (0.1 N at 30⁰ below the horizontal) for 5s after which time it strikes and sticks to the body, B, of mass 3.00 kg, the force being removed at that instant. What will the speed of the combined masses be?

    2. Relevant equations

    3. The attempt at a solution
    ok so i found the i cmpt of the force, from this i found the impulse. since the initial velocity is 0 the impulse is equal to the initial momentum, from there i solved and got v=0.086m/s could some please check this... thanks
