The correct answer is C. I leave an attached image to have a clearer idea of the light process that uses the Light when entering the eye. When you have farsightedness, the image is formed behind the eye so the defective effect is generated.
What is sought with the lenses is to correct this condition and put the image back at the point of the retina.

Answer:
X = 2146.05 m
Explanation:
We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.
We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:
X = Vt (1)
However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:
t = √2h/g (2)
Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:
t = √(2*2500)/9.8
t = 22.59 s
Now replacing into (1) we have:
X = 95 * 22.59
<h2>
X = 2146.05 m</h2>
This is the distance where the package should be released.
Hope this helps
Forces are added. Acceleration would be the thing decreasing if the airplane is in the air and flying forward, which I am assuming as no context is given.
Even if the airplane was stationary an the ground forces would still be added. Acceleration is the consequence of force, not the same thing.
