A fish swimming at a constant speed of 0.5 m/s suddenly notices a shark appear behind it . 5 seconds later the fish is swimming in the same direction at a speed of 2.5 m/s What is the fish, s acceleration

A fish swimming at a constant speed of 0.5 m/s suddenly notices a shark appear behind it. 5 seconds later the fish is swimming in the same direction at a speed of 2.5 m/s, the fish's acceleration - 0.4 m/s squared.

Given:

time t = 5.0 s

Inititial velocity - 0.5 m/s

Final velocity = 2.5 m/s

accelaeration a= ?

Solution:

Placing the given values:

=>

=> = 0.4 m/s squared

Thus, A fish swimming at a constant speed of 0.5 m/s suddenly notices a shark appear behind it. 5 seconds later the fish is swimming in the same direction at a speed of 2.5 m/s, the fish's acceleration - 0.4 m/s squared.

0.4 m/s²

Explanation:

Given:

v₀ = 0.5 m/s

v = 2.5 m/s

t = 5 s

Find: a

v = at + v₀

2.5 m/s = a (5 s) + 0.5 m/s

a = 0.4 m/s²

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.
