�mmh A automobile is travel at 20.0 m/s, and the driver sees a traffic light turn red. After ~ 0.530 s (the reaction time), the driver uses the brakes, and also the auto decelerates at 7.00 m/s2. What is the stopping distance the the car, together measured native the allude where the driver an initial sees the red light?

We need to break this right into two parts.� The driver will travel a street while the reaction time is occurring.� because that this component we have actually �, an acceleration

*
�, and a time
*
�.� The equation we must use is

*

So

*

Once the braking occurs and the auto is under acceleration

*
� (Note: - sign because we space braking), we still have actually �, we recognize
*
�, and we are searching for stopping distance.� usage relationship

*

Solve because that distance

*

So the full stopping distance is found by including

*




You are watching: What is the distance she passes after noticing the obstacle before fully stopping?
