Chapter- 2. Kinematics in One-Dimension I. A car is traveling at 18. 5 m/s, and the driver notices that a traffic light just turned red. After the reaction time of the driver, 0.330 s later, the driver applies the brakes, and the car decelerates at 5.00 m/s2. Find the total stopping distance of the car, as measured from the point where the driver first sees the red light. (Hint: this distance is the sum of the two distances; one traveled...

A driver is traveling at 30.0 m>s when he sees a moose crossing the road 80.0 m ahead. The moose becomes distracted and stops in the middle of the road. If the driver of the car slams on the brakes, what is the minimum constant acceleration he must undergo to stop short of the moose and avert an accident?
