Answer:
The maximum electric power output is
Explanation:
From the question we are told that
The capacity of the hydroelectric plant is
The level at which water is been released is
The efficiency is 0.90
The electric power output is mathematically represented as
Where is the potential energy at level h which is mathematically evaluated as
and is the potential energy at ground level which is mathematically evaluated as
So
here
where V is volume and is density of water whose value is
So
substituting values
The maximum possible electric power output is
substituting values
The boat's position relative to its starting point
is determined by
where is its initial velocity,
is its acceleration, and
is time. After
, the boat has traveled
