Vo = 93 km/h = 25.8 m/s
Lat a be the acceleration.
Distance travelled during reaction time = 25.8 * (reaction time)
Distance travelled while decelerating = Vo^2/(2|a|)
Add the times.
Anyone with a reaction time of 3.0 seconds should not be driving. Recheck the numbers in the problem.
Determine the stopping distances for a car with an initial speed of 93 km/h and human reaction time of 3.0 s for the following accelerations:
-4.00 m/s^2
-8.00 m/s^2
