    Answer: C.

    250 kg-m/s

    Explanation:

    Given that the

    Mass M = 1,500 kg

    Force F = 500 N

    Time t = 0.5 seconds

    From Newton’s second law of motion which state that the rate of change of momentum is proportional to the applied force.

    F = mV/t

    Ft = mV

    Where ft = impulse: the product of time and applied force

    Substitutes force and time into the formula

    Ft = 500 × 0.5 = 250 Ns
