-- 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?
Assuming the rock is dropped (initial velocity is 0), the time it takes for the rock to reach the ground can be calculated using the formula: time = sqrt(2 * distance / gravity). The acceleration due to gravity is approximately 32 ft/s^2. Plugging in the values, the time it takes for the rock to reach the ground would be approximately 3 seconds.
How fast would a human fall at 1000 ft minus all air resistance?
Assuming no air resistance, a human falling from 1000 feet would accelerate at a rate of 32.2 ft/s^2, which is the acceleration due to gravity. The time it would take for the human to reach the ground can be calculated using the free fall equation t = sqrt(2h/g), where h is the height (1000 ft) and g is the acceleration due to gravity (32.2 ft/s^2). This would give a time of approximately 8 seconds.
How long is the jumper in free fall if the parachute opens at 1000 ft?
Assuming the jumper free falls from an airplane at a typical altitude of 12,000 ft, it would take approximately 12 seconds to fall the first 1000 ft. If the parachute opens at 1000 ft, the jumper will then have a controlled descent for the remaining distance to the ground.
How fast do objects free fall near earth?
Objects in free fall near Earth fall at a rate of approximately 9.8 meters per second squared, known as the acceleration due to gravity. This means that for each second an object falls, it will increase its speed by 9.8 m/s.
How long does it take a rock to hit the ground from 630 ft tall building?
Assuming the rock is dropped from rest and neglecting air resistance, it would take about 5.6 seconds for the rock to hit the ground from a 630 ft tall building. This is derived from the kinematic equation: distance = 0.5 * acceleration due to gravity * time^2.
