You can't determine the momentum of the objects with just their mass. Here's why:

* Momentum is a vector quantity: This means it has both magnitude (size) and direction.

* Momentum depends on velocity: The formula for momentum is:

* Momentum (p) = mass (m) x velocity (v)

To find the momentum, you need to know the velocity of each object.

For example:

* If both objects are at rest (velocity = 0), their momentum is 0.

* If one object is moving at 5 m/s to the right and the other is moving at 10 m/s to the left, they will have different momentum values.

Let me know if you can provide the velocities of the objects, and I can calculate their momentum!
