A theoretical answer can be derived if you ignore energy losses (such as air resistance). Assume the diver starts off with a downward velocity of zero, and accelerates under gravity with no energy losses.
Thus his acceleration is equal to g (the gravitational field strength) in a downward direction. This is about 9.8 N kg-1, or 9.8 m s-2, depending on how you write it (both are equivalent).
At the top of his dive, he has a kinetic (moving) energy of zero, and potential energy given by:
PE = m g h
where m is his mass (in kilograms), and h is the height of the diving board (in this case, 10 metres)
This is converted into kinetic energy as he falls. When he hits the water, we can say that he has a potential energy of zero, and kinetic energy given by:
KE = m v2 / 2
Energy cannot be created or destroyed, so the potential energy at the top of the dive must be equal to the kinetic energy at the bottom.
m g h = m v2 / 2
g h = v2 / 2
2 g h = v2
v = (2 g h)1/2
= (2 x 9.8 m s-2 x 10 m)1/2
= 14 m s-1
The true value (allowing for air resistance) may be slightly lower than this.
it depends on the weight of the diver. is would be faster if the diver was a yougn child, forsay, and faster if it were a sumo wrestler!!
NO IT DOESN'T. Whoever posted that is an idiot! If you drop a feather, a Bowling ball, and a vacuum cleaner in a vacuum they will all fall at the same time, you idiot! You are stupid! The SA to weight is all that would matter in what you are referring to and not enough to matter in the presented circumstances!
~50k/h, by the way.
The resistance of water when jumping off a diving board is called drag, and it is caused by the water's viscosity and density. Drag opposes the motion of the diver, making it harder to move through the water and causing the sensation of resistance.
The average upward force exerted by the water can be calculated using the impulse-momentum theorem. First, find the diver's initial velocity before hitting the water using kinematic equations. Then, use the formula F_avg = mĪv/Īt, where m is the diver's mass, Īv is the change in velocity, and Īt is the time over which the force is applied.
This is due to the high resistance or drag force exerted by the water as the diver enters it. The drag force quickly slows down the diver's speed, leading to a rapid deceleration compared to the relatively small gravitational force that initially accelerated the diver's fall. This difference in forces causes the diver to stop much faster in water than in free fall air.

The potential energy of the diver can be calculated using the formula: PE = mgh, where m is the mass of the diver (150 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height of the diving board (10 m). Therefore, the potential energy of the diver is PE = 150 kg * 9.81 m/s^2 * 10 m = 14,715 J.
64.9559kg if the gravity acceleration is 1

A typical diver watch is water resistant in depths of about 200 - 300 meters. Diver watches are made of high grade materials able to withstand the change in atmospheric pressure under water and with proper care can easily be used in salt water and fresh water applications.
Agitating water before high diving helps reduce the surface tension of the water, which in turn lessens the impact force on the diver's body upon entry. This can help prevent injuries and make the landing smoother for the diver.
This is due to the high resistance or drag force exerted by the water as the diver enters it. The drag force quickly slows down the diver's speed, leading to a rapid deceleration compared to the relatively small gravitational force that initially accelerated the diver's fall.

High water pressure (at depth) causes nitrogen to be dissolved into the bloodstream. Ascending too fast can cause the nitrogen gas to 'bubble out'. These bubbles can cause the diver to suffer a heart attack - with possibly fatal consequences. If a diver rises no faster than the air bubbles they're breathing out, it gives the body time to dispel the nitrogen through the bloodstream and out through the lungs.
One possible answer involves a forest fire and a very charred scuba diver. During a fire a water carrying helicopter collected water from the sea in order to extinguish it. However the helicopter also picked up the scuba diver, in the sea water, and the diver was killed when he was dumped in the middle of the fire, most likely from a high altitude.
