For any isolated system linear momentum remains constant for the system whether collision between inclosed body take place or not.
Momentum of system before collision=momentum of system after c
ollision. MaUa+ MbUb= MaVa+ MbVb
Derivation
1. F= ∆ P/∆t
= m(∆t/∆ t)
m.a
F= m.a
2.FAB=FBA

Answer:
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)
