Question

state and Prove the conversation of linear momentum​

Answer 1

Answer:

law of conservation of linear momentum of the system is always conserved if no external force acts on an object or system of objects.

.... Hence this question implies that if no external forces acts on the system of two colliding balls,the total momentum is conserved.

Explanation:

Answer 2

Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. This idea was used by Newton to derive the law of conservation of momentum. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)
