12-17. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes causing his car to decelerate at 12 ft/s. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes he decelerates at 15.ft/s2. Determine the minimum distance d be tween the cars so as to avoid a...

The driver of a 1.19 103 kg car traveling on the interstate at 35.0 m/s (nearly 80.0 mph) slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead. After the brakes are applied, a constant kinetic friction force of magnitude 7.96 103 N acts on the car. Ignore air resistance. (a) At what minimum distance should the brakes be applied to avoid a collision with the other...

The speed limit in a school zone is 45 km/h. A driver traveling at this speed sees a child run onto the road 20 m ahead of his car. He applies the brakes, and the car decelerates at a uniform rate of 11.0 m/s2. If the driver's reaction time is 0.55 s, will the car stop before hitting the child?What is the stopping distance of the vehicle?

Review Interactive Solution 2.33 in preparation for this problem. Suppose a car is traveling at +17.3 m/s, and the driver sees a traffic light turn red. After 0.226 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 5.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

Review Interactive Solution 2.33 in preparation for this problem. Suppose a car is traveling at +19.8 m/s, and the driver sees a traffic light turn red. After 0.381 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 7.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

Review Interactive Solution 2.33 in preparation for this problem. Suppose a car is traveling at +20.7 m/s, and the driver sees a traffic light turn red. After 0.307 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

Review Interactive Solution 2.33 in preparation for this problem. Suppose a car is traveling at +16.3 m/s, and the driver seesa traffic light turn red. After 0.512 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 7.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light? Number Units the tolerance is +/-5%

Tests reveal that a normal driver takes about 0.75 s before he or she can react to a situation toavoid a collision. It takes about 3 s for a driver having 0.1% alcohol in his or her system to dothe same. If such drivers are traveling on straight road at 50 km/h and their cars can decelerateat 0.6 m/s2, determine the shortest stopping distance d for each of these drivers from themoment they see the pedestrians. Moral: If you must...
