The truck drives on a horizontal road with a constant velocity. It eventually bumped the wall due to reckless driving. In each of the following cases, the car stopped in the same amount of time. Which has the largest and smallest stopping force?
**Please draw all necessary diagrams showing shockwaves.**
Due to a road crash, the southbound direction of a 2-lane, 2-way highway was completely closed. Before the event, vehicles were running at 40 kph with density of 20 vpk. It took 35 minutes before the road got cleared again due to road crash investigation, waiting for emergency response team, and clearing of debris. The traffic stream follows Greenshield's model with free flow speed of 50 kph and jam density of 90 vpk.
a.) Draw all necessary diagrams showing shockwaves.

- 3. Answer the following questions a) Derive an equation to estimate speed of shockwave. b) On a one-way freeway segment with a flow of 1000 veh/h and density 100 veh/mile, a fully loaded truck enters the stream, reducing the flow to 500 veh/h, and moves for 5 miles at a speed of 20 mph before exiting. The vehicles behind the trucks cannot overtake the truck and are forced to go behind the truck with the speed of the truck at jam density. Determine how many passenger cars will be in the platoon formed due to the truck's entry by the time the truck leaves the freeway. Given: Speed of the stream after the truck's departure= 80 miles/h, Jam Density = 200 veh/mile.arrow_forwardA public school holds its flag ceremonies every Monday from 7:00 AM to 7:15 AM.
