    Answer

    1m/s

    Explanation

    Given that:

    Mass of first blob = 2kg = m1

    Velocity of blob = 4m/s = v1

    Mass of second blob = 6kg = m2

    Velocity of blob = 0m/s = v2

    To find:

    Final velocity = Vf

    This question is of inelastic collision which is any collision between objects in which some energy is lost.

    Formula to be use: (m1*v1) + (m2*V2) = Vf (m1 + m2)

    (2*4) + (6*0) = Vf (2+6)

    8 + 0 = Vf (8)

    8 = Vf (8)

    Vf = 1 m/s

    So the speed of two blobs immediately after colliding = 1 m/s
