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
16 kg-m/s northeast
16 kg-m/s northeast
8 kg-m/s northeast
8 kg-m/s northeast
8 kg-m/s southwest
8 kg-m/s southwest
16 kg-m/s southwes
The momentum of the first object is 12 kg-m/s northeast, while the momentum of the second object is 4 kg-m/s southwest. When they collide and stick together, their momentum after the collision can be found by adding their momentums.
12 kg-m/s northeast + 4 kg-m/s southwest = 8 kg-m/s northeast
Therefore, the correct answer is:
8 kg-m/s northeast
