Suppose a car is traveling at +24.7 m/s, and the driver sees a traffic light turn red. After 0.262 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 4.00 m/s². What is the stopping distance of the car, as measured from the point where the driver first notices the red light?

You are driving down the highway late one night at 20 m/s when a deer steps onto the road 40 m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 12 m/s2. How much distance is between you and the deer when you come to a stop? distance:   m What is the maximum speed you could have and still not hit the deer? maximum speed:

George, the absent-minded professor, drives his car 5.0 miles due east alonga straight road to the grocery store. Upon arriving there 15 minutes (0.25 h) after he left home, he suddenly realizes he forgot his grocery list. He immediately turns around and heads back towards home. After travelling 6.8 miles due west in 12 minutes (0.20 h), the car runs out of gas. What is his average speed during the not-quite-completed trip?

While driving at 45.0 mi/hr (20.1 m/s) on a straight portion of Route 9 West, Randi notices that the traffic light has turned red at the intersection directly ahead. Randi applies his brakes, slows his car down at a steady rate, and brings his car to rest, while traveling the 60.0 m distance to the stop line (at the red light). 21. While he is slowing down, the acceleration of Randi's car has a magnitude of A. 6.73 m, В. 16.9 m 2. 169 m/: А. С. 33,8 т D. 9.80 m E. 3.37 m / 22. How much time passes as Randi's car slows down from 45.0 mi/hr to 0 m/s? A. 20.68 s. B. 5.97 s. C. 2.66 s. D. 2.99 s. E. 0.596 s. 23. While Randi's car is slowing down, his car's acceleration is A. directed straight down towards the Earth's center. B. equal to zero. C. directed straight upwards. D. directed parallel to the car's velocity. E. directed antiparallel to the car's velocity.
