    Answer:

    the impulse experienced by this object is 4 Ns

    Explanation:

    Given;

    mass of the object, m = 3 kg

    velocity of the object, v = 4 m/s

    resistive force, F = 20 N

    duration of impact, t = 0.2 s

    The impulse experienced by this object is calculated as follows;

    J = F x t

    J = 20 x 0.2

    J = 4 Ns

    Therefore, the impulse experienced by this object is 4 Ns
