Question

Explain conservation of lines
momentum in case of firig
of Pistol and explosion of
materials​

Answer 1

“In an isolated system (no external force), the algebraic some of the momenta of bodies, along any straight line, remains constant and is not changed due to their mutual action and reaction on each other”.

This can be verified by a following simple experiment.

Consider a body ‘A’ of mass ‘m1’ moving with a velocity \vec{u_{1}}  strike against another body ‘B’ of mass m2,moving with velocity  in same direction as shown in the below figure. Two bodies remain in contact with each other for small time ‘?t’. They get separated and move with velocities\vec{v_{1}}  and \vec{v_{2}} after collision.

Answer 2
