(N/A) Stopping distance is the distance a vehicle travels after the brakes are applied until it comes to a complete stop.
It depends on the initial velocity $(v_0)$ of the vehicle and the deceleration $(a)$ produced by the brakes.
Using the third equation of motion,$v^2 = v_0^2 + 2as$,where $v$ is the final velocity $(0 \ m/s)$,$v_0$ is the initial velocity,$a$ is the negative acceleration (deceleration),and $s$ is the stopping distance.
Setting $v = 0$,we get $0 = v_0^2 - 2as$,which simplifies to $s = \frac{v_0^2}{2a}$.
