Yes, two objects that have the same mass and velocity will always have the same momentum.

Here's why:

* Momentum is a measure of an object's mass in motion. It's calculated by the formula: Momentum (p) = mass (m) x velocity (v)

* If two objects have the same mass (m) and the same velocity (v), then when you plug those values into the momentum formula, you will get the same result for both objects.

Therefore, two objects with the same mass and velocity will always have the same momentum.
