On seeing red light ahead, a driver takes 0.3 s to apply the brakes. This is called the reaction time of the driver. If he was initially driving at a speed of 36km/hr and application of the brakes causes a deceleration of `4.0m//s^(2)`. Calculate the distance travelled by the car after he sees the red light.

Explanation

To solve the problem step by step, we will break it down into two parts: the distance traveled during the driver's reaction time and the distance traveled during the deceleration phase after the brakes are applied.

### Step 1: Calculate the distance traveled during the reaction time (d1)

1. **Identify the initial speed**: The driver is initially driving at a speed of 36 km/hr.
2. **Convert speed to meters per second**:
\[
\text{Speed in m/s} = \frac{36 \text{ km/hr} \times 1000 \text{ m/km}}{3600 \text{ s/hr}} = 10 \text{ m/s}
