Answer 2

Answer:

⇒m1v1+m2v2=m1u1+m2u2. ⇒ Final momentum (pf) = Initial momentum (pi). Thus, we conclude that during the interaction between the two balls, momentum before collision is equal to total momentum after collision. Thus, the momentum of the system is conserved in the absence of external forces.
