3. Flow on a road is ql=1800veh/hr/lane, and density is kl=14.4 veh/km/lane. To reduce speeding on a section of highway, a police cruiser decides to implement a rolling roadblock, and to travel in the left lane at the speed limit (v2=88km/hr) for 10 km. This ensures that no overtaking is done by the vehicles in this platoon. After the police cruiser joins, the platoon density increases to 20 veh/km/lane and flow drops. Find: (a) How many vehicles will be in the platoon when the police car leaves the highway (b) How long it will take for the queue to dissipate
