The car stops at the traffic light. It then moves along a straight path so that its distance from the light is given by x(t) = bt² – ct³, where b = 2.40 and c = 0.120. a) Calculate the average velocity of the car for the time interval t= 0 to t = 10.0 s. b) Determine the car's instantaneous velocity at t = 0, t = 5s andt= 10s. c) How long after starting from rest is the car again at rest.

You arrive at a home to find a young man deceased in his bedroom at his parents home. His parents state he came home from work at about 5pm the night before then went out some clubs and came home in the early morning. In his pants you find 700 in cash and an atm receipt from that night time stamped 7:30 pm withdrawing $40.00 dollars from his bank. What various scenarios can explain findings ? Detail at least two possible scenarios for what might have happened include details including 1. Where he might have been 2. Who he might have been with 3. What activities he might have been engaged in 4.how the evidence you have found might support/ negate your theory

The Ministry of Health is planning to build a mobile application software to screen passengers (citizens and expatriates) in Muscat and Salalah airport. Mobile Application Software contains many modules like User Registration, taking photo, store medical information and generate reports for MoH. The Mobile App software should be tested and implemented in a short time because of COVID-19. A leading software company is chosen for the fully functional software development in order to provide a high speed delivery. From your understanding which life cycle model might be chosen to develop the mobile app software and Justify it with at least five points.
