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. The crossing guard holds up her stop sign, and the driver is paying attention well. The car moves at a
constant velocity of 11 m/s for 2.3 seconds while the driver reacts, then slows down at a constant rate
of -4.5 m/s2. What is the stopping distance for the car in this situation?

the answer is to check all of them! they all apply well at least i think so!
