Answer

Explanation:

Step1: Identify the kinematic - equation

We use the equation $v = v_0+at$, where $v$ is the final velocity, $v_0$ is the initial velocity, $a$ is the acceleration, and $t$ is the time.

Step2: Determine the values of variables

The initial velocity $v_0 = 24\ m/s$, the final velocity $v = 0\ m/s$ (the car stops), and the acceleration $a=- 8.0\ m/s^2$.

Step3: Rearrange the equation to solve for $t$

From $v = v_0+at$, we can get $t=\frac{v - v_0}{a}$.

Step4: Substitute the values into the formula

$t=\frac{0 - 24}{-8}=\frac{-24}{-8}=3\ s$.

Answer:

A. 3 s
