    Explanation:

    The momentum of any object is given by the product of mass and velocity with which it is moving i.e.

    p = mv

    Momentum is a vector quantity. It means we can resolve it into rectangular components.

    If the car is moving with a speed of 20 m/s in North direction, its momentum is given by :

    p_y=20m\ \hat{j}\ kg-m/s …..(1)

    If the car is moving with a speed of 20 m/s in East direction, its momentum is given by :

    p_x=20m\ \hat{x}\ kg-m/s ….(2)

    It is clear from equation (1) and (2) that the magnitude of momentum is same but the direction of momentum is different in both cases.
