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.
