    0 kgm/s

    Explanation:

    The momentum is the product of mass (m) and velocity (v).

    Initially the velocity of truck is 0 m/s so the product of mass and velocity becomes 0.

    It does not matter what is the weight of truck, because the velocity will make the product of m*v = 0

    It does not matter what is the momentum of car.
