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)

Answer 1

To find the momentum after the collision, we need to add the momentum of both objects.

The first object has a momentum of 12 kg-m/s traveling northeast, while the second object has a momentum of 4 kg-m/s traveling southwest. Since the second object is traveling in the opposite direction, we can consider its momentum as negative.

Therefore, the momentum before the collision is: 12 kg-m/s + (-4 kg-m/s) = 8 kg-m/s

When the two objects collide and stick together, they become one object, so their momenta are combined.

The momentum after the collision is 8 kg-m/s.
