A Smart City Traffic Management System Scenario: A smart city initiative aims to integrate real-time traffic data from multiple zones into a centralized platform. The system will help in managing congestion, optimizing the signal of traffic lights, and predicting traffic patterns with the help of historical data. Design the software architecture for this traffic management system by using design patterns and architectural principles. • Identify key design patterns you would use (at least three patterns). • Give reasons for the pattern choices selected. • Clearly explain how these patterns work with each other in the entire system architecture. • Mention how this design might pose any challenges and show possible ways to overcome such difficulties.

Impulse Impulse = force x time Impulse = F x ?t (Units: kg m/s) Note the units for momentum and Impulse are the same. This tells us that they physically related. Finally, when we relate impulse and momentum, we find that in fact the Impulse = Change in Momentum F?t = $mv_f - mv_i$ or F?t = ?p B. A 10 N force is applied to a 2.0 kg object for 5.0 s. What is the impulse? ?p = 10 x 5 = 50 kg m/s C. If in problem 'B' the object started from rest, find its final velocity
