Assuming that it takes 0.10 s for the driver to react before applying the brakes, what is the stopping distance (the distance from the point where the driver first sees the need to stop to the point where the car comes to a stop) for a car traveling at 25 m/s if the deceleration due to the brakes is 3.5 m/s2?

  1. vf^2=vi^2+2ad

    solve for d. Now, add that to the distance in reaction time, 25*.1 meters
