One object is traveling northeast with a momentum of 12 kg-m/s, while a second object is traveling southwest on the same path as the first object with a momentum of 4 kg-m/s. When the two objects collide, they stick together. What is the momentum after their collision?(1 point)

To find the momentum after the collision, we need to add the momenta of the two objects before the collision.
The first object has a momentum of 12 kg-m/s traveling northeast. Since momentum is a vector quantity, we can represent this momentum as (12 kg-m/s) northeast.
The second object has a momentum of 4 kg-m/s traveling southwest. Again, since momentum is a vector quantity, we can represent this momentum as (4 kg-m/s) southwest.
When the two objects collide and stick together, their momenta combine.
Adding the two momenta, (12 kg-m/s) northeast and (4 kg-m/s) southwest, we get (12 kg-m/s + 4 kg-m/s) = 16 kg-m/s northeast.
Therefore, the momentum after their collision is 16 kg-m/s northeast.
