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...

009 10.0 points The driver of a car traveling at 36.3 m/s ap- plies the brakes and undergoes a constant deceleration of 1.28 m/s How many revolutions does each tire make before the car comes to a stop, assuming that the car does not skid and that the tires have radii of 0.27 m? Answer in units of rev

009 10.0 points The driver of a car traveling at 43.7 m/s ap- plies the brakes and undergoes a constant deceleration of 1.59 m/s. How many revolutions does each tire make before the car comes to a stop, assuming that the car does not skid and that the tires have radii of 0.22 m? Answer in units of rev.

An old car is traveling down a long, straight, dry road at 25.0 m/s when the driver slams on the brakes, locking the wheels. The car comes to a complete stop after sliding 235 m in a straight line. If the car has a mass of 755 kg, what is the coefficient of kinetic friction between the tires and the road?

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?
