Answer:
m₁ x △v₁ = -m₂ x △v₂
Step-by-step explanation:
Note that:
• Momentum is the product of mass and velocity
,
• The law of conservation of momentum states that the total momentum before collision equals the total momentum after collision provided that there is no external force acting upon the system
Considering the given options, the only option that can represent the law of conservation of momentum is:
m₁ x △v₁ = -m₂ x △v₂
