Answer 2

Explanation:

Multiply Velocity by Mass

Multiply the initial velocity of each object by its mass. Add these two products together to get the total momentum. For example, if both objects have a mass of 5 kilograms, one is at rest and the other is moving at 10 meters per second. The calculation would look like this: 5 x 10 + 5 x 0.
