You can use Newton's equations of motion:
At the top of the climb its velocity u = 0 m/s
Its acceleration is acceleration due to gravity a ≈ 9.8 m/s
Time of descent t = time of ascent = 3.00 s
(I'll assume positive is towards the ground)
v = u + at
≈ 0 m/s + 9.8 m/s² × 3.00 s
= 29.4 m/s
HOWEVER, this is the velocity (towards the ground) reached when the rock has returned to height from which it was thrown (released) above the ground - unless the rock was "thrown" by an explosive force at ground level, the rock will not have reached the ground at this point: there is still the distance from which it was "thrown".
Which means its final velocity at ground level can be found using:
v² = u² + 2as
v = velocity it hits the ground
u ≈ 29.4 m/s (as found above)
s = distance above ground from which the rock was "thrown" = height_of_throw m
a = acceleration due to gravity ≈ 9.8 m/s
→ v² = u² + 2as
→ v ≈ √((29.4 m/s)² + 19.6 m/s² × height_of_throw m)
= √(864.36 + 19.6 × height_of_throw) m/s
Its the air resistance that causes the free falling body to reach its terminal velocity
The object opposes the air and while falling of the object the initial velocity will become zero , and the final velocity will have some value's this is how air will resist the velocity of falling object ...........
The speed when falling objects no longer accelerates due to air resistance is the maximum falling velocity.
terminal velocity is the final maximum velocity of a falling object.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
Neglecting air resistance his velocity after 1 second will be 9.81 m/sec or 32.2 ft/sec.

The speed when falling objects no longer accelerates due to air resistance is the maximum falling velocity.
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
terminal velocity is the final maximum velocity of a falling object.
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.
The maximum velocity of a falling person is about 200 miles per hour; at that point the air resistance does not allow further acceleration.
You did not exactly finish your question. Are you looking for velocity, force or some sort of bounce? Velocity can be found with v2 = v1t + 1/2at2 or v2 = acceleration times distance Kinetic energy is KE= 1/2mv2
is falling as fast as air resistance will allow it to.
