Impulse is a change in the amount of linear momentum of an object due to the action of a force on that object during a time interval:
When a car moves at constant velocity, it does not experience any change in its linear momentum. Then, there is no impulse involved in an object moving at constant velocity.
On the other hand, when a football player collides with another, they exchange linear momentum through a force that they apply on each other. Simiarly, there is an exchange of linear momentum when a racket hits a ball.
Therefore, the correct choice is option D)
A footbal player colliding with another, or a racket hitting a ball.
