Answer:

[tex]a=6\ m/s^2[/tex]

Explanation:

Given that,

Initial speed, u = 0.5 m/s

Final speed, v = 2 m/s

Time, t = 0.25 s

Let a be the acceleration of the mosquito. Using first equation of motion as follows :

v=u+at

Put all the values,

2=0.5+0.25a

So,

[tex]a=\dfrac{2-0.5}{0.25}\\\\a=6\ m/s^2[/tex]

So, the acceleration of the mosquito is equal to [tex]6\ m/s^2[/tex].
