Step-by-step 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.
