A car starts from an acceleration of 18 m/s^2. Find the time needed for the car to reach 33 m/s

Since we are given the acceleration and final speed, we will determine the time using the expression:


v=at

That is:


33m/s=(18m/s^2)t\Rightarrow t=(33m/s)/(18m/s^2)
\Rightarrow t=(11)/(6)s\Rightarrow t\approx1.83s

So, it will take 11/6 seconds, that is approximately 1.83s.
