    The momentum of bath cars is 40000 Ns which make the difficulty to stop each car in aspect of fprce is the same.

    Explanation:

    Momentum (P) = mass (m) * velocity (v)

    For car A,

    P = m * v = 1000 * 40 = 40000 Ns

    For car B,

    P = m * v = 4000 * 10 = 40000 Ns

    Force (F) = Momentum change (ΔΡ) / time taken (t)

    F = ΔΡ/t

    When stopping the car the momentum changes from 40000 Ns to 0

    So momentum change in both cars is the same. So to stop the two cars in a given time (t) you need the same force, which means you will feel same difficulty.
