A 0.142 kg baseball on a 0.8 meter table has 1.11 J of potential energy. It falls. How much kinetic energy, in Joules, will it have on the way down when it reaches a height of 0.25 meters? Assume
mechanical energy is conserved.

0.04544 J

Explanation:

KE= 1/2 the mass times V squared

KE=1/2(0.142) * (0.8)^2

KE= 0.071 * 0.64

KE=0.04544

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 .
