Let,
[tex]$v_{1 i} a n d v_{2 i}$[/tex] be the two spheres of the speed before impact
[tex]$v_{1 f} a n d v_{2 f}$[/tex] be the speed after impact.
By using the law of conservation of linear momentum,
[tex]$0=M v_{1 f}+(2 M) v_{2 f} v_{2 f}=-\frac{1}{2} v_{1 f} \cdots \cdots(1) v_{1 f}=-2 v_{2 f}$[/tex]
The negative sign indicates the sphere approaches each other.
What is the law of conservation of linear momentum?
The conservation of momentum states that, within a few problem domain, the quantity of momentum stays constant; momentum is neither created nor destroyed, however only modified thru the movement of forces as defined through Newton's laws of motion. Dealing with momentum is extra tough than coping with mass and energy due to the fact momentum is a vector quantity having each a magnitude and a direction. Momentum is conserved in all 3 physical directions on the identical time. It is even extra tough whilst coping with gas due to the fact forces in one path can have an effect on the momentum in any other path due to the collisions of many molecules
