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
What Wind moving water and falling rock are examples of what type of energy?
Wind moving water and falling rock are examples of kinetic energy, which is the energy of movement.
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).
What type of energy is Wind moving water and falling rock are examples of?
Wind energy is a type of kinetic energy, as it is produced by the movement of air. Moving water generates hydropower, which is a form of mechanical energy. Falling rock releases potential energy, which then transforms into kinetic energy as the rock falls.
Do fast moving rivers carry more smaller or larger particlees of sediment?
Fast moving rivers tend to carry more smaller particles of sediment. This is because the faster flow of water is better able to erode and transport finer particles compared to larger ones.
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
Suppose a rock in free fall is dropped off a cliff after falling 5 seconds what is it speed?
The speed of the rock after falling for 5 seconds would be approximately 49 m/s, neglecting air resistance. This speed is the result of the acceleration due to gravity, which is approximately 9.81 m/s^2.
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?
The rock would likely undergo abrasion, breaking off small pieces and smoothing its surface as it is carried downstream by the force of the fast moving river. Over time, this process can break the rock down into smaller fragments and reshape its overall appearance.
Is a falling rock a kinetic reaction?
A falling rock is an example of kinetic energy, not a kinetic reaction. Kinetic energy is the energy possessed by a moving object, while a reaction typically refers to a chemical or physical process that involves changes in molecular structure or composition.
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.
