Since we are given the acceleration and final speed, we will determine the time using the expression:
[tex]v=at[/tex]That is:
[tex]33m/s=(18m/s^2)t\Rightarrow t=\frac{33m/s}{18m/s^2}[/tex][tex]\Rightarrow t=\frac{11}{6}s\Rightarrow t\approx1.83s[/tex]So, it will take 11/6 seconds, that is approximately 1.83s.
