Objects 1 and 2 collide and stick together. Which best describes the momentum of the resulting single object?

It is less than the momentum of object 1 but greater than the momentum of object 2.

It is greater than the momentum of object 1 but less than the momentum of object 2.

It is equal to the momentum of object 1 minus the momentum of object 2.

It is equal to the momentum of object 1 plus the momentum of object 2.

Answer explanation

Law of momentum states that initial momentum EQUALS final momentum.
