The school zone in front of your school has a posted speed limit of 25 mi/h, which is about 11 m/s. Let’s examine the stopping of a car in several different situations. A child appears to be running into the street ahead. It takes 2.3 seconds for the driver to react and begin to break, but this time at a rate of -7.5 m/s^2. What is the stopping distance for the car in this situation?
