In traveling a distance of 3.3 km between points A and D, a car is driven at 86 km/h from A to B for t seconds and 42 km/h from C to D also for t seconds. If the brakes are applied for 4.8 seconds between B and C to give the car a uniform deceleration, calculate t and the distance s between A and B.
Two cars A and B are stopped at a traffic light, waiting for the light to change from red to green, see Figure 3. Car B is 6 meters behind car A. When the light turns green, car A starts accelerating at a rate of 0.3 m / sec2, while car B departs 2 seconds later and accelerates at a rate of 0.8 m / sec2. Determine the speed each car was carrying when they are side by side.
The car is traveling at a constant speed through a dip in the road. The radius of curvature of the road at point A, the bottom of the dip is 471m. What speed of the car (kph) would result in an acceleration of magnitude 0.2g when the car is at A? use 3 decimal places
The “reaction time” of the average automobile driver is about 0.7 s. (The reaction time, in this context, is the interval between the perception of a signal to stop and the application of the brakes.) If an automobile can slow down with an acceleration of 8 m/s2, compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 40 kph. Express your answers in meters.

(TRAFFIC AND HIGHWAY ENGINEERING)Figure below shows vehicles traveling at constant speeds on a two-lane highway between sections X and Y with their positions and speeds obtained at an instant of time by photography. An observer located at point X observes the four vehicles passing point X during a period of T sec. The velocities of the vehicles are measured as 70, 70, 65, and 50 (km/h), respectively. Calculate the flow, density, time mean speed, and space mean speed.
