Five minivans and three trucks are traveling on a 1.5 mile circular
track and complete a full lap in 90.0, 100.0, 102.0, 80.0, 90.0, 101.0, 85.0, and 95 seconds, respectively.
Assuming all the vehicles are traveling at constant speeds:
(a) what is the time-mean speed and space-mean speed of the minivans?
(b) what is the time-mean speed and space mean speed of all vehicles?
Four race cars are traveling on a 2.5-mile tri-oval track. The four cars are traveling at constant speeds of 195 mph, 190 mph, 185 mph, and 180 mph respectively. Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point.
Find the TSM, SMS, q, and k
Assume you are observing traffic in a single lane of a highway at a specific location. You measure the average headway and average spacing of passing vehicles as 3.2 seconds and 20 m, respectively. Calculate the flow, average speed, and density of the traffic stream in this lane.

- You are riding home from a party and the driver is drunk. The car is traveling at 60 mi/hr. Suddenly, a child steps into the road ahead. Since the driver is drunk his reaction time has been slowed by 1s. How far will the car travel before the driver begins to stop?
