0.5kg ball moving at a speed of 3m/s rolls up a hill what is thet height

0.459 m.

Explanation:

To calculate the height, use 3rd equation of motion as

Here v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height.

As ball moving up so acceleration due to gravity becomes negative i.e -g and at maximum height v = 0.

Therefore equation becomes,

Given u = 3 m/s and g = 9.8 m/s^2.

Substitute the given values, we get

h = 0.459 m

Thus, the height of hill is 0.459 m.

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.
