A driver takes 0.20 s to apply the brakes after he sees a need for it. This is called the reaction time of the driver. If he ils driving a car at a speed of 54 km/h and the brakes cause a deceleration of `6.0 m/s^2`, find the distance travelled by the car after he sees the need to put the brakes on.

Explanation

(distance covered during 0.20 s) + (distance covered until rest)
`=(15xx0.25)+[18.75]=21.75m`
