The acceleration is in fact at a maximum at that same instant.

Sounds counter-intuitive at first sight but it must be right.

For an instant, the velocity is zero.  The acceleration is in fact at a
maximum at that same instant.

When the velocity is zero the acceleration is zero however the force which is the cause of an acceleration is maximum. An acceleration is the rate of change of velocity in (meters per second) per second so if velocity is zero then acceleration is zero because there is no change.

On another note in my rush to devise a better way to remove the float in the tube I forgot one small detail. More float means less water, as such we are always losing water and the idea I proposed is unworkable. Any way we look at it the water which is displaced is the water which must be replaced... bummer.

We need a float at the top and at the bottom that are self-synchronized (linked together), similar to this concept.  The tube will go through the bottom float and into the water.  As the water is displaced from the tube, the bottom float will rise and the top float will..... However, when we solve one problem then we create another problem, lol.

F = mA.  Where force is at a maximum, so is the acceleration, even if the velocity is zero.

F = mA.  Where force is at a maximum, so is the acceleration, even if the velocity is zero.

The force is zero, the acceleration is zero, and the velocity is zero.  Below is a snapshot of the results from an acceleration calculator.  I'm using the Planck time of 10^-43 for the time interval in our equation.  However, we can use any time interval and it doesn't change the result.  So, we plug in the calculator's result of 0 into our force equation and we have F = m * 0, F = 0.  Acceleration only applies to a moving object.  Acceleration doesn't apply to a stationary object.  Saying the acceleration is at the maximum is another inversion of the truth.  Saying the Force is at the maximum is another inversion of the truth.
