Answer:

Final speed of the body, v= 15.61 m/s

Step-by-step explanation:

It is given that,

Initial speed of a body, u = 7.58 m/s

Uniform acceleration,
$a=3.62\ m/s^2$

Time, t = 2.22 s

We need to find the speed of the body after this time. The first equation of motion is as follows :

v=u+at

v=7.58+3.62* 2.22

v = 15.61 m/s

So, the speed of the body after 2.22 seconds is 15.61 m/s. Hence, this is the required solution.
