Help! Conservation of Momentum

  1. Feb 27, 2012 #1
    1. The problem statement, all variables and given/known data

    Object 1 has a mass of 2.8 kg and is moving eastward with a velocity of 7.7 m/s. It collides with a stationary object. After the collision object 1 recoils with a velocity of -2.2 m/s What is the mass of object 2?


    2. Relevant equations

    As far as I know:

    Conservation of Momentum
    Po=P
    m1v1=m2v2
    m=mass


    3. The attempt at a solution

    I keep trying to solve by using m1v1=m2v2

    m2 = m1v1/v2

    What does conservation of momentum mean in words?
    What does the momentum equation you've written (m1 v1 = m2 v2) mean (in words)?
