    Where the m1 and m2 is the mass of two object. U1 and U2 are the initial velocity of hockey pucks. V1 and V2 are the final velocity of Hockey Pucks.

    m2=2kg The initial velocity of both pucks are 0. The v1=8m/s. All you have to do now is find v2

    0=4-2v

    -4=-2v

    v=+2m/s

    Answer: + 2
