A limousine driver notices a stop sign while traveling 55 km/hr. What is the acceleration of the limousine if it comes to a complete stop in 4.3 s? Round to 1 decimal place if necessary.

he kicked it 10 feet straight up into the air? i think this works.

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.
