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.

the correct statement is

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

this is because of conservation of momentum which says that the total momentum remains constant before after the collision.

total momentum before collision = total momentum after collision

so

momentum of object 1 before collision + momentum of object 2 before collision = momentum of combined object of object 1 and object 2 after collision.

its a 5.5 n

glad that
