The driver is looking at her phone and has a total reaction time of 4.6 seconds as the car is moving at a constant speed of 11 m/s. If the driver slams on her brakes and slows down at a rate of -8.2 m/s?, what is the stopping distance for the car in this situation?
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?  b). A child appears to be running into the street ahead. It takes 2.3 seconds for the driver to react and begin to brake, but this time at a rate of -7.5 m/s2 . What is the stopping distance for the car in this situation?   c). The driver is looking at her phone and has a total reaction time of 4.6 seconds as the car is moving at a constant speed of 11 m/s. If the driver slams on her brakes and slows down at a rate of -8.2 m/s2 , what is the stopping distance for the car in this situation?
A drunk man was driving his car at a speed of 25.0 m/s (or 90 kph) when he saw a cow in the middle of the road, 50.0 m away from him. It took him 0.400 s to react at which the car was moving at constant speed. After that, he stepped on the brakes to stop at a rate of 6.00 m/? . Is this acceleration enough to save him and the cow from an accident?
