Aman runs with a speed of 6 m/s off a platform that is 10
mabove the water. how fast is he moving when he hits thewater?
ignore air

15.2m/s

Explanation: Solution

Initial velocity(u)=6 meters per second

Final velocity(v)=?

Gravitational force (g) =9.8meter per second(square)

Height=10meters

Formula=

V(square)=u(square)+2*g(m/s(square)*height (m)

Velocity =√6(square)+√ 2*9.8*10

Velocity = √6*6+√2*9.8*10

Velocity= √36+√196

Velocity=√232

Velocity=15.2m/s.

This means that the man will be running at 15.2meters per second at the time he hits the ground. His final speed was increased because of the impact of the force of gravity (g).

what are the statements? x

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.
