Solution

The correct option is C No, because the external force is not zero
The kick is an external force on the ball. Hence, the momentum will change or the momentum will not remain conserved.

Q. The total momentum 'p' of two balls remain conserved after they collide because the net external force acting on the system is .

The principle of conservation of linear momentum states that if in any assigned direction the net external force on a system is zero, then the linear momentum of the system will remain constant. Thus it can be concluded that if the momentum of a two-particle system is initially zero, then because of internal forces they will move in opposite directions to conserve momentum.
