The Gulf Stream off the east coast of the United States can flow at a rapid 3.9 m/s to the north. A ship in this current has a c

Answer:
degrees west of south
Explanation:
The ship should go to the south at an equal rate as the water flows north so the velocities balance and the ship just move west.
As far as the water is concerned, the ship goes 3.9 m / s to the south, but much remains to the west. To find out that the triangle is drawing. 3.9 m/s point down side and the hypotenuse is 11cos(angle) = \frac{adjacent}{hypotaneous}.

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
