Answer:
Kinetic energy of diver at 90% of the distance to the water is 9000 J
Explanation:
Let d is the distance between the position of the diver and surface of the pool.
Initially, the diver is at rest and only have potential energy which is equal to 10000 J.
As the diver dives towards the pool, its potential energy is converting into kinetic energy due to law of conservation of energy, as total energy of the system remains same.
Energy before diving = Energy during diving
(Potential Energy + Kinetic Energy) = (Kinetic Energy + Potential Energy)
When the diver reaches 90% of the distance to the water, its kinetic energy
is 90% to its initial potential energy, as its initial kinetic is zero,i.e.,
K.E. = 
K.E. = 9000 J

The speed of the wave is mathematically given as
v=2266.66m/s
A long wave with a period of about 15 minutes will travel across the oceans at a speed of approximately v=2266.66m/s
<h3>
Speed of the wave</h3>
Question Parameters:
A long wave with a period of about 15 minutes
Generally the equation for the Wave velocity is mathematically given as
v=\lambda * frequency
Where
f=1/t
Therefore
v=\lambda * frequency
v=\lambda * 1/t
Therefore, with wavelenght of the ocean as 34km
v=34*1000*1/15
v=2266.66m/s
