    The answer for the following problem is explained below.

    Therefore the change in the momentum is 240 kg m/s

    Explanation:

    Given:

    net force(F_{net}) = 120 N

    time (t) = 2 seconds

    To solve:

    change in momentum(Δp)

    We know;

    F_{net} = Δp÷t

    Δp = F_{net} × t

    Δp = 120 × 2

    Δp =240 kg m/s

    Therefore the change in the momentum is 240 kg m/s
