Aaron's normal response time to apply the car brakes is 0.7 seconds. aaron's response time doubles when he is tired. how far will aaron's car travel during the time it takes him to apply the brakes when his car is moving at 30 meters per second whe he is tired? show the solution.

Aaron's car is moving at speed of 30 m/s

His reaction time is given as 0.7 s

but when he is tired the reaction time is doubled

Now we need to find the distance covered by his car when he is tired during the time when he react to apply brakes

So here since during this time speed is given as constant so we can say that distance covered can be product of speed and time

So here we can use

So the car will move to 42 m during the time when he apply brakes
