The cheetah is one of the fastest accelerating animals, for it can go from rest to 29.4 m/s in 5.35 s. if its mass is 101 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. express your answer in (a) watts and (b) horsepower.

8159 W, 10.9 hp

Explanation:

The work done by the cheetah is equal to the kinetic energy gained, so we can write:

where

m = 101 kg is the mass of the cheetah

u = 0 is the initial speed

v = 29.4 m/s is the final speed

Substituting,

Now we can calculate the power developed by the cheetah, given by:

where

t = 5.35 s

is the time taken. Substituting,

And keeping in mind that

1 hp = 746 W

We can also convert into horsepowers:

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.

the answer is a. hope this .
