Given that the initial velocity is

$v_i=\text{ 45 m/s}$

The final velocity is

$v_f=\text{ 0 m/s}$

The acceleration is a = -4 m/s^2

We have to find the time taken to stop the car completely.

The formula to calculate time is

$t=\text{ }((v_f-v_i))/(a)$

Substituting the values, the time will be

$\begin{gathered} t=(0-45)/(-4) \\ =11.25\text{ s} \end{gathered}$

Thus, the time taken is 11.25 s
