To find the diver's velocity upon hitting the water, we can use the equations of motion under gravity. The final velocity (v) can be calculated using the formula (v = \sqrt{2gh}), where (g) is the acceleration due to gravity (approximately (9.81 , \text{m/s}^2)) and (h) is the height (9.6 m). Substituting the values, we get (v = \sqrt{2 \times 9.81 , \text{m/s}^2 \times 9.6 , \text{m}} \approx 13.9 , \text{m/s}). Thus, the diver's velocity when he hits the water is approximately 13.9 m/s.

When a diver ascends too quickly from deep waters, they risk developing decompression sickness, commonly known as "the bends." This occurs because the rapid change in pressure causes dissolved gases, primarily nitrogen, to form bubbles in the bloodstream and tissues. Symptoms can range from joint pain and dizziness to severe neurological issues, and in extreme cases, it can be life-threatening. To avoid this, divers are advised to ascend slowly and make safety stops during their ascent.

Aquatic respiratory systems primarily function through gills, which extract dissolved oxygen from water. Water enters the mouth, flows over the gill membranes, and exits through openings, allowing oxygen to diffuse into the blood while carbon dioxide diffuses out. This process is often assisted by a countercurrent exchange mechanism, where water flows in the opposite direction to blood flow, maximizing oxygen uptake. Overall, this system efficiently supports the metabolic needs of aquatic organisms.

In Vanuatu, the minimum age for scuba diving is typically 10 years old for junior certifications, offered by major diving organizations like PADI and SSI.
