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,

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 = 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.
