a.compute the space mean speed of the traffic, in kph.b.compute the flow of traffic.c.compute the density of traffic.
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.
5) A car is traveling along a straight road with an acceleration of a = 1/4 * s ^ (1/4) (m/s^ 2 ) Determine the velocity when the car travels 2 (m).

Determine the distancearrow_forwardA car is stopped at an entrance ramp to a freeway; its driver is preparing to merge. At a certain moment while stopped, this driver observes a platoon of vehicles a distance x0 upstream and initiates the merge maneuver. The platoon approaches the entrance ramp at a constant speed v. The stopped car can accelerate from speed 0 to v at uniform acceleration rate a. Find the latest time at which the stopped car can safely start the merge maneuver; i.e., derive an expression for the “latest safe start time” in terms of the variables x0, v and a. Assume this latest time enables the platoon to maintain its constant speed and "just touch" the merging car's trajectory.
