Two cars are traveling side by side on level terrain at 100 km/h on a road with a coefficient of adhesion of 0.8. The driver of car 1 has a 2.5-s perception/reaction time and the driver of car 2 has a 2.1-s perception/reaction time. The drivers are able to stop their respective cars in the same distance after seeing a roadway obstacle. If the braking efficiency of car 2 is 0.78, determine the braking efficiency of car 1. (Assume minimum theoretical stopping distance.)

A driver on a level two-lane highway observes a truck completely blocking the highway. The driver applied the brakes and utilized the maximum longitudinal friction of 0.45 between the wet pavement surfaces and tires. The vehicle stopped only 10 m from the truck. If the driver was driving at 100 km/h, how far was she from the truck when she first observed it (assume perception-reaction time is 1.5 seconds)? How far was she from the truck at the moment the brakes were applied
Car A is traveling at a constant speed vA = 127 km/h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.0 m/s2 until a speed of 171 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Neglect any nonrectilinear motion of P.
The distance traversed during perception-reaction time is equal to 10 meters if the speed of the car is 10 meters per second, and the perception-reaction time of the driver is 1 second. TRUE OR FALSE
You are to determine the duration of the yellow light at a highway intersection. Assume that cars will be approaching the intersection traveling at 70 mph, and that the reaction time of the driver is 2.5 sec and that cars achieve a deceleration of 1/8 of the gravitational acceleration. if g=32.2 fps^2, a. how long must the traffic light remain yellow to allow drivers to come to stop before the traffic light turns red? b. what is the minimum distance of a car from the intersection when the lightturns yellow to ensure that it comes to a full stop before the intersection?
A car (SUV) is to overtake a bus as it enters an acceleration lane. The speed of the SUV is 80 kph initially. The bus is at the same speed as the SUV. Given the perception reaction time as 2.70 seconds and the average acceleration of the vehicle is 2.55 m/s2, solve the following: a. The distance (in ft) traversed during the perception and reaction time and during the initial acceleration to the point of encroachment on the left lane.b. The distance (in yard) travelled by the passing vehicle occupies the left lane if the opposing vehicle travelled at 75 kph and the time for the passing vehicle to occupy the left lane is 20 seconds. c. The minimum passing sight distance (in m) if the SUV's velocity to overtake the bus is 55.92 miles per hour while the distance between the opposing vehicle and the SUV after its maneuver is 295 ft. The time for the SUV to occupy the left lane is 0.23 minutes.
