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)
Responses
8 kg-m/s southwest
8 kg-m/s southwest
16 kg-m/s northeast
16 kg-m/s northeast
16 kg-m/s southwest
16 kg-m/s southwest
8 kg-m/s northeast
8 kg-m/s northeast
To solve this problem, we need to add up the momenta of the two objects before the collision to find the total momentum after the collision.
The first object has a momentum of 12 kg-m/s in the northeast direction.
The second object has a momentum of 4 kg-m/s in the southwest direction.
Since both objects are on the same path, their momenta can be added together. The direction of the final momentum will be determined by the majority direction.
12 kg-m/s (northeast) + 4 kg-m/s (southwest) = 16 kg-m/s (northeast)
Therefore, the momentum after the collision is 16 kg-m/s northeast.
The correct answer is:
16 kg-m/s northeast
