�mmh A auto is traveling at 20.0 m/s, and also the driver watch a traffic light rotate red. After ~ 0.530 s (the reaction time), the driver applies the brakes, and also the vehicle decelerates at 7.00 m/s2. What is the avoiding distance of the car, as measured indigenous the suggest where the driver first sees the red light?

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

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

*

So

*

Once the braking occurs and the car is under acceleration

*
� (Note: - sign due to the fact that we space braking), we still have �, we recognize
*
�, and also we are in search of stopping distance.� usage relationship

*

Solve for distance

*

So the total stopping distance is discovered by including

*




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