You throw a 3.00-n rock vertically into the air from ground level. you observe that when it is 15.3 m above the ground, it is traveling at 25.3 m/s upward use the work-energy theorem to find the rock's speed just as it left the ground. express your answer with the appropriate units. ? use the work-energy theorem to find its maximum height. express your answer with the appropriate units. ?

it may be wrong but i think its a

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.

pretty sure it's false
