Discuss and compare the fundamental attribution error and self-serving bias.

Identify any one busy street on your community with large volumes of surface traffic comprised of vehicles, cyclists, and pedestrians. Explain how you would carry out problem identification, and if a problem is found to exist, discuss how you would assess the need for a solution.

You are the city engineer of a large city. Name and describe any one system of systems (SOS) that falls under your control. List one concern that is likely to be associated with your SOS’s physical structure, operation, or physical condition. How would you assess the overall technical performance of (a) any one component system of the SOS and (b) the entire SOS? For the SOS, list and discuss any three costs or “disutilities” associated with the system.

Your campus bus transit corporation is considering switching its fleet from gasoline to hybrid. From the systems perspective, what advice would you give?

The city of Imaginopolis, which is located near White River, has an elaborate system of levees to protect the city from flooding during high-water events. The levees were built over 50 years ago and many of them are showing signs of structural distress. Using a systems perspective, how would you draw up a program to rehabilitate the levee system under budgetary constraints over a 5-year period?

A nursing home located near a busy freeway suffers from excessive noise from the freeway traffic. Describe fully a solution that you would recommend to resolve the situation using the systems approach.

The following information applies to every part of this problem: A 1-kg mass hanging from a spring stretches it .3924 m in its equilibrium position. The spring is initially compressed to .5 m above the equilibrium point and released with an initial downwards velocity of 2 m/s. Use 9.81 m/s² for the acceleration due to gravity.

(a) Assuming that there is no damping and no additional force applied to the spring, write down and solve an initial value problem giving the position of the spring at time t. Plot the result using https://www.desmos.com/calculator and include a screenshot of your plot.

(b) Assuming that there is no damping but that an additional force of F(t) = 6 cos(4t) is applied to the spring, write down and solve an initial value problem giving the position of the spring at time t. Plot the result using https://www.desmos.com/calculator and include a screenshot of your plot.

(c) Compare the plots from parts (a) and (b). How did the plot change when an external force was applied? What stayed the same?

(d) Assuming that there is a damping force proportional to the mass’s velocity with proportionality constant 26 kg/s and no additional force applied to the spring, write down and solve an initial value problem giving the position of the spring at time t. Plot the result using https://www.desmos.com/calculator and include a screenshot of your plot.

(e) Assuming that there is a damping force proportional to the mass’s velocity with proportionality constant 26 kg/s and that an additional force of F(t) = 6 cos(4t) is applied to the spring, write down and solve an initial value problem giving the position of the spring at time t. Plot the result using https://www.desmos.com/calculator and include a screenshot of your plot.

(f) Compare the plots from parts (d) and (e). How did the plot change when an external force was applied? What stayed the same?
