Question

Please help me with this..
and show all the steps properly...​

Answer 1

`given \\ final \: velocity \: (v) = 18m {s}^( - 1) \\ initial \: velocity \: (u) = 8m {s}^( - 1) \\ time \: (t) =5s \\ \\ \\ we \: know \: that \\ acceleration = ((final \: velocity - initial \: velocity))/(time) \\ = > a = (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)`

This is the answer.
