1.Which objects gets to the bottom the fastest?
2.Which object has the greatest kinetic energy at the bottom?
3.Calculate the translational velocity for each object.

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 .
