•The light planet is faster,
Explanation:
Since we have two planets whose momentum have been found to be the same, and we know that one has a higher mass than the other, then the light planet can be said to be faster moving.
This way, the momentum of the light planet can measure up.
- Momentum is the product of mass and velocity of a body.
Momentum = mass x velocity
If a body is heavier than another, it will have more mass than it.
To compensate for the momentum, the lighter body must have a higher velocity.
This way, their momentum will be the same.
