Answer:
See the explanation below
Step-by-step explanation:
No matter at what height a body is dropped, the body will always accelerate to the same reason, which corresponds to Earth's gravitational acceleration.
g = 9.81 [m/s²]
That is, in the first second the velocity is 9.81 [m/s] = 9.81 [m/s²] x 1 [s]
Now in the second 2; 19.62 [m/s²] = 9.81 [m/s²] x 2 [s]
And in the third second 29.43 [m/s²] = 9.81 [m/s²] x 3 [s]
And etc.
