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 :
[tex]p_y=20m\ \hat{j}\ kg-m/s[/tex] .....(1)
If the car is moving with a speed of 20 m/s in East direction, its momentum is given by :
[tex]p_x=20m\ \hat{x}\ kg-m/s[/tex] ....(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.
