Answer:
Explanation:
When a person jumps into a swimming pool and is uninjured while the same person is injured when he jumped from the same height onto the concrete floor, this can be explained by the impulse-momentum concept.
When a person jumps into the swimming pool, water provides cushioning and gradually decreases the velocity of a person with a considerable amount of time. While on the other hand concrete floor does not provide the cushioning effect as it is rigid.
So, force is imparted at a short amount of time causing more injury compared to the swimming pool case.
