[tex]given \\ final \: velocity \: (v) = 18m {s}^{ - 1} \\ initial \: velocity \: (u) = 8m {s}^{ - 1} \\ time \: (t) =5s \\ \\ \\ we \: know \: that \\ acceleration = \frac{(final \: velocity - initial \: velocity)}{time} \\ = > a = \frac{v - u}{t} \\ = > a = \frac{18m {s}^{ - 1} - 8m {s}^{ - 1}}{5s} \\ = > a = \frac{10m {s}^{ - 1}}{5s} \\ = > a = \frac{2m {s}^{ - 1}}{s} \\ = > a = 2m {s}^{ - 2} [/tex]
This is the answer.
