Question: The speed limit in a school zone is 40 km h
The speed limit in a school zone is 40 km/h (about 25 mi/h). A driver traveling at this speed sees a child run onto the road 13 m ahead of his car. He applies the brakes, and the car decelerates at a uniform rate of 8.0 m/s2. If the driver’s reaction time is 0.25 s, will the car stop before hitting the child?
