You can jump 3 m (10 feet) off of a diving board and into a swimming pool and be uninjured. However, if you jumped from the same height onto concrete it would be very bad. Use principles of impulse and momentum to explain why this is the case.

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.
