14.20m/s/s or 14.20m/s2 (the 2 is suppose to be the square sign)

Why aren't all rocks the same?
Rocks are not the same because, they come from either a Volcano, or they are broken from the Earth's ground. So this causes it to be different shapes and sizes.
Whats wrong with quarrying?
Quarrying is a place that has rocks that has been excavated from the ground. This is also known as an open-pit mine.
Suppose a rock is dropped off a cliff with an initial speed of 0 m per sec What is the rocks speed after 5 seconds in m per sec if it encounters no air resistance?
9.8m/s(5)= 49
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rocks speed after 3 seconds in ms if it encounters no air resistance?
The acceleration of gravity is 9.8 m/s2Speed after 3 sec = (9.8 x 3) = 29.4 m/s
What are real life examples of inclined planes?
Civil engineers need to know how much they have to slope the ground around roadways. If the slope isn't right we end up with debris sliding down embankments into roadways. Falling rocks, anyone?
A 12 kg rocks falls from rest off a cliff and hits the ground in 1.5 s.without considering air resistance what is the rock s velocity just before it hits the ground?
The velocity is gravity acceleration x time or (9.8)(1.5) = 14.7 m/s. The velocity is not dependent on the mass.
What happens when rocks fall down a cliff?
It falls and break
What is a rock at the top of a cliff that suddenly falls?
Weathering makes rocks at the top of a cliff suddenly fall.
If you rolled two rocks of a cliff which one would hit the ground first?
it depends wich two kind of rocks are u rolling???
If rock at rest falls off a cliff and hits the valley below after 3.5 seconds what is the rocks velocity as it hits the ground?
The final velocity of a falling object can be worked out by the use of the formula a = (v - u)/t a = acceleration due to gravity = 9.8 m.s-2 v = final velocity = unknown u = initial velocity = 0 t = time taken = 3.5s Factor these known values into our equation 9.8 = (v - 0)/3.5 rearrange the formula to workout the unknown value v = 9.8 x 3.5 Final velocity on impact with valley floor = 34.3 m.s-1 with a downwards direction

What is cliff retreat?
A cliff retreat is a form of natural erosion. Rocks in the face of the cliff are broken down by wind and water (rain, waves, etc). The material in the cliff is loosened, and parts of the cliff face collapse. Eventually, an entire section of the cliff will fall into the sea, meaning that the cliff edge has retreated. The pace of cliff retreat is determined by the strength of the rocks in the cliff face, more than the cliff's height. It also most often occurs where the base of the cliff is continually being saturated by water, weakening the rock further.
Which types of rocks are formed above ground?
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
Where does a pronghorn sleep at night?
On a cliff. Between some rocks.
Where did the cliff dwellers build their homes and what were they made from?
I Know some cliff dwellers were in arizona and new mexico. They used the cliff itself and mostly just rocks. I have been to a cliff dwelling in arizona called Montezuma's Castle. They were pretty basic. They used ladders made of wood to get up the cliff to their homes. They definitely used mud and rocks.
