a traveling railroad car A, strikes an identical car, B, at rest. If the cars lock together as a result of the collision, calculate how much of the inital kinetic engery is transformed to thermal or other forms of energy

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 .

this would be about 43%

well clustered together.
