-- At the beginning, when it's dropped, its speed is zero.
-- At the end, when it hits the ground, its speed is 802.5 feet per second (547.2 mph).
-- During the 24.92 seconds when it's falling, its speed increases smoothly at the rate
of 32.2 feet per second faster every second than it was a second earlier.
These numbers are true if the rock is not falling through air. If there happens to be
air in some or all of its path, then the numbers are somewhat different, and they'd
depend on the shape, size, and weight of the rock. Even knowing those details ...
which you haven't included in the question ... a calculation in advance would be
fiendishly complicated, and the only real way to accurately predict the answer
would be to take the rock up to 10Kft, drop it, and time it.

A rock falls from a cliff 144 ft high How long does it take the rock to reach the ground?
an object will fall at around 50ft every second, so around 3 seconds.
How fast do objects free fall near earth?
32 ft per second squared- However, due to air resistance, the final speed will top out at about 250 mph for a streamlined object.
How fast does air with a velocity pressure of 0.20 in w.g. move through a round duct?
1800 ft min
How long does it take a rock to hit the ground from 630 ft tall building?
s = 1/2 at^2 where a = 32 ft/sec/sec t = time = 6.27 seconds neglecting air resistance
What are the factors that affect the rate of fall?
Gravity and resistance (friction). Friction will only come into play on a fall from a long distance. This will be in the form of air resistance. If you are falling a short distance, gravity is the only force. The fastest you will be able to fall is at a rate of 9.81 ft/s^2.
