List the four equations of linear motions (also referred to as the kinematics equations). in your notations, consider "u" to be the initial velocity of the body, "v" the final velocity," t" the time interval, "a" the acceleration and "s" the distance covered by the body .

The answer to your question is below:

Explanation:

Data

u = initial velocity

v = final velocity

t = time interval

a = acceleration

s = distance

1.- s = ut + (1/2) at²

2.- v = u+ at

3.- v² = u² + 2as

4.- s = (u + v) t / 2

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
