Answer 2

Answer:

The above equation is used when we've to state the equity between the momentum before an event and momentum after an event.

It is based on law of conservation of linear momentum.

This equation particularly describes the situation WHEN A BODY OF A MASS AND WITH CERTAIN VELOCITY BREAKS UP INTO TWO DIFFERENT MASSES AND BOTH THE MASSES MOVE WITH SOME VELOCITIES.
