A2-kg bowling ball is 1 meter off the ground on a post when it falls just before it reaches the ground it is traveling 4.4m/s assuming that there is no air resistance witch statement is true a) the mechanical energy is conserved b) the initial potential energy is less then the final kinetic energy c) the mechanical energy is not conserved d) the initial potential energy is greater then the final kinetic energy

Your answer will be A) The mechanical energy is conserved (:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

it is a negative acceleration
