Answer:
hey mate here is your answer
Explanation:
Why is momentum conserved when a ball hitsa vertical wall? Almost in every book on physics, there's an example of conservation of momentum when the ball that is moving horizontally in the air, hits some massive wall. They claim that the return speed of the ballwhen it bounces off is the same as it was before the hit.
