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

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
