    Answer: Impulse = 4 kgm/s

    Explanation:

    From the question, you’re given the following parameters:

    Momentum P1 = 12 kgm/s

    Momentum P2 = 16 kgm/s

    Time t = 0.2 s

    According to second law of motion,

    Force F = change in momentum ÷ time

    That is

    F = (P2 – P1)/t

    Cross multiply

    Ft = P2 – P1

    Where Ft = impulse

    Substitute P1 and P2 into the formula

    Impulse = 16 – 12 = 4 kgm/s

    The magnitude of the impulse is therefore 4 kgm/s.
