Acceleration due to gravity is approx 9.8 metres/second2
So after 2.3 seconds, the velocity of the rock is 9.8*2.3 = 22.54 metres/second

What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
What was the acceleration of that rock that after 4 seconds is moving at 40 meters per second?
If it started at rest, 4x40 is 160 metres per second
How far does a five pound rock fall in five seconds?
In order to come up with an answer, we have to impose a couple of rules: 1). we're trying this on the earth 2). we're ignoring the effects of air 3). it's not moving at the beginning of the 5 seconds ... that's when you drop it from your hand Then the rock falls 400 ft in five seconds. What's really interesting is that it doesn't matter how much it weighs. ALL rocks fall the same distance in 5 seconds.
Suppose a rock in free fall is dropped off a cliff After falling 5 seconds its speed will be 100?
False v=1/2 a t2 t=5s a=9.81m/s2 v=122.625 m/s
Is 5 seconds of summer rock?
they are a type of pop and rock type of band
How fast is a rock moving When it hits the bottom of a 39.2 m cave after 4 seconds?
0 km/h or 0 mph. Objects accelerate at 10m/s so after 4 seconds the rock would have already hit the bottom of the cave.
If you drop a rock from a great height about how fast will it be falling after 5 seconds neglecting air resistance?
The object will be falling at 49 m/s.This is solved by multiplying the force of gravity (9.8 m/s) by the time you're calculating (5s).
Do fast moving rivers carry more smaller or larger particlees of sediment?
Fast moving rivers are capable of carrying larger rock particles than slow moving rivers.
What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
What is the weight of a 12kg rock after if falls for 1.5 seconds?
If it's falling near the earth's surface, the weight is 27.56 pounds (rounded), regardless of how long or how far it's been falling.
What is a fast moving wave of rock and ash that rushes down the side of a volcano?
Pyroclastic Flow
What would happen to a rock from weathering by a fast moving river?
It would erode and maybe crack
Is a falling rock a kinetic reaction?
There is no such thing as a kinetic reaction. Any moving body has kinetic energy. When a rock falls, its gravitational potential energy is transformed to kinetic energy.
How fast does a rock fall in the ocean?
A falling rock in vacuum accelerates at 9.8 meters per second2 ... the acceleration of gravity at the earth's surface.A falling rock in air has a smaller acceleration than in vacuum, because of air resistance;the exact figure depends on the rock's weight and shape.A falling rock in water has an even smaller acceleration than it air, because of water resistance; the exact figure again depends on the rock's weight and shape.
What are three examples of objects with Kinetic energy?
A falling rock. A cannonball in flight. A tetherball swinging around the pole. Anything that's moving.

How does saturns rings float without falling?
The rings of Saturn do not float. The rings consists of pices of rock and ices. Each fragment is on orbit around Saturn. An object in orbit does not float. Rather, it is in continuous freefall, but is moving so fast "sideways" that it constantly misses.
