Two cars are traveling along a straight line in the same direction, the lead car at 25.7m/s and the other car at 29.2m/s. At the moment the cars are 39.7m apart, the lead driver applies the brakes, causing her car to have an acceleration of -1.99m/s2. How long does it take for the lead car to stop?
What is the distance it travels during this time?
Assuming that the chasing car brakes at the same time as the lead car, what must be the chasing car's minimum negative acceleration so as not to hit the lead car?
How long does it take for the chasing car to stop?

Two cars are traveling in the same lane in the same direction. They are 120 ft apart and are both traveling at 60 mph. The roadway is level. The leading car hits a disabled milk truck and comes to an instatenous stop. The perception-reaction time of the driver in the trailing car is ½ second. The driver of the trailing car locks the brakes and skids into the lead car. The coefficient of friction between the roadway and skidding tires...

The brakes are applied to a car traveling on a dry, level highway. A typical value for the magnitude of the car's acceleration is 4.85 m/s2. If the car's initial speed is 28.5 m/s, how long does it take to stop and how far does it travel, starting from the moment the brakes are applied? time to stop? stopping distance?

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...

A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...
