If two objects of the same mass are going two speeds, which has more momentum? The faster or slower object?

The faster object

Explanation:

Sure they may have the same mass but the item with more speed is going to take more force to cancel out or stop its motion. It would take less force to halt the slower object as less momentum is behind it.

i don't know that i agree with that but what's the question ?

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.
