An object is thrown straight up into the air. The object leaves the person’s hand with an upward velocity of magnitude 27 m/s. Assume that the object is in free fall, i.e., neglect air resistance. Draw a motion diagram and graphs (two graphs: one for vertical position vs. time, and one for vertical velocity vs. time) from the time when the object leaves the person’s hand to 5.0 seconds later. Include all the information on the graph that you can determine about the object’s motion, such as its position and velocity at 5.0 seconds. Assume that the person does not catch the object or interfere with it during the 5.0 seconds time interval.

A hockey stick exerts a horizontal force of magnitude 3.0 N on a 0.25-kg puck. While under the influence of the stick's force (and possibly some other forces), the puck moves 2.0 m. a) Is it possible that the stick does 6.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement while the force acts? b) Is it possible that the stick does - 3.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement? c) Is it possible that the stick does -6.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement? d) Is it possible that the stick does 6.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement? e) If the puck possesses an initial speed of 4.0 m/s, and then 4.0 J of work is done on the puck, find its final speed. Ignore friction. f) If the puck possesses an initial speed of 4.0 m/s, and then -2.0 J of work is done on the puck, find its final speed. Ignore friction.

Place the following energy states in order of their least net carbon dixide emission into the atmosphere, where 1. = lowest net carbon, and 5. = highest net carbon.

In your calculation, take into account:

1. How much carbon dioxide (or CO2 equivalent) is emitted per unit energy generated.
2. If the source is renewable, how much carbon dixide (or CO2 equivalent) is removed from the atmosphere each year by that resource.
3. How much energy is needed to produce and deliver that energy source.

Oils. Petroleum fractions, plant oils, and similar viscous substances, ccommonly combined with lighter distillates to form diesel fuels for truck and rail engines.   

Gaseous. Hydrocarbons, hydrogen and carbon monoxide mixtures present in gaseous state at room temperatures which, when combined with oxygen (burned) release heat and/or light.   

Solid fuels. Fossil carbonates (coals and peat), carbonized woody materials (coke, charcoals, and biochars), and lignite (woody) fuels including wood, pelletized grasses, etc. burned directly in their solid state.  

Distillates. Highly flammable liquids (liquid at room temperature) distilled from petroleum (gasoline), fermented plant starches (ethanol) and plant oils ("green" kerosene), used in both turbine (jet) and internal combustion engines.

Problem 4-34 Multiple Products, Break-Even Analysis, Operating Leverage Carlyle Lighting Products produces two different types of lamps: a floor lamp and a desk lamp. Floor lamps sell for $30, and desk lamps sell for $20. The projected income statement for the coming year follows: Check figures: 2. $277,778 4. Break-even revenue = $294,118 OBJECTIVE 0 0 Sales Less: Variable costs Contribution margin Less: Fixed costs Operatingincome $600 ,000 400,000 200,000 150,000 $ 50,000 The owner of Carlyle estimates that 60 percent of the sales revenues will be produced by floor lamps and the remaining 40 percent by desk lamps. Floor lamps are also responsible for 60 per- cent of the variable expenses. Of the fixed expenses, one-third are common to both products, and one-half are directly traceable to the floor lamp product line. Required: I. Compute the sales revenue that must be earned for Carlyle to break even. 2. Compute the number of floor lamps and desk lamps that must be sold for Carlyle to break even . 3. Compute the degree of operating leverage for Carlyle Lighting Products. Now assume that the actual revenues will be 40 percent higher than the projected revenues. By what percentage will profits increase with this change in sales volume? 4. CONCEPTUAL CONNECTION What is the theory behind the operating leverage concept?

Topic 8 Spending and Output in the Short Run

8.1 Explain the errors of the following arguments made by an economicsstudent:

a) “The textbook said that a higher interest rate lowers investment, but that doesn’t make sense. I know that if I can get a higher interest rate, I am certainly going to invest more in my savings account.”

b) “The newspaper said that the recent recession was caused by a decline in investment. This can’t be true. If there had just been a decline in investment, the only firms hurt would have been construction firms and other firms selling investment goods. In fact, many firms experienced falling sales during that recession, including department stores and firms selling consumer electronic products.”

8.2 Company A in country X is considering the investment in a project with the following (estimated) cost and benefit. The project has a life of 3 years and has zero value after the third year.

a) Suppose in year 0 Company A could borrow or lend at an annual interest rate of 4%. Explain clearly with calculation whether Company A will invest in this project.

b) Based on your answer in part (a) explain how an increase in interest rate to 5% will affect Company A’s investment decision.

c) There is a concern about the unemployment problem in country X and the lack of investment demand is regarded as one of the major reasons of unemployment. Suppose other firms in country X will be affected in the same way as Company A as described in part (a) and (b) above. Use the Keynesian model to explain the process of how a change in interest rate may help to solve the unemployment problem.

8.3 Consider the following Keynesian model: Consumption:

C = 200 + 0.7Yd

Lump-sum tax: T0 = 50

Proportional Tax Rate: t = 0.2

Government Expenditure: G = 435

Planned Investment: I = 300

Exports: X = 100

Imports: M = 0.06Y

Yd: Disposable Income

Numbers are in billion dollars.

a) Each row corresponds to one possible output level. Fill in the remaining columns of the table given the equations given above.

b) What is the equilibrium output level of this economy?

c) What is the level of unplanned investment at the output level of 1500 and at the level of 15 2500? If it is not in equilibrium, describe how the economy would adjust to the equilibrium in each case.

d) What is the change of equilibrium output when government expenditure increases to 560? Explain your steps. What kind of policy is it?

e) If investment decreased to 175 billion dollars under policy uncertainty, how does it change the equilibrium output level? Is the change in equilibrium output larger than the change in investment? Why?

f) What factors would affect the size of expenditure multiplier? Briefly explain

Part B: Based on the financial statements that were prepared with this data, complete the following financial ratio calculations and provide a narrative discussion of these results as compared to industry averages (provided.)

Ratios required:

Ratio Industry Average

1. Profit margin 3.2%

2. Return on assets (use ending assets) 6.0%

3. Return on common equity (use ending common equity) 15.6%

4. Receivable turnover (use ending receivables) 8.5 x

5. Inventory turnover (use ending inventory) 12.0 x

6.Fixed asset turnover (use ending fixed asset balance) 5.75 x

7. Total asset turnover (use ending assets) 1.89 x

8. Current ratio 3.10

9. Quick ratio 1.40

10. Debt to total assets (use ending assets) 37.0%

Your solution should include the required ratios for each year and then provide a narrative discussion regarding the results as they compare to the industry averages. This analysis should discuss whether or not Smith's Inc. is better or worse than the industry average but it should not stop there. You should also include a discussion as to why or how the difference can be explained, i.e., the reason for the variance. The final solution is to be provided in the Word document, with the module and part clearly identified. The narrative discussion will reference the appropriate ratio and the comparison to the appropriate industry average.

explain how the banking system 'creates' money independent from the amount of currency in the economy. In your own words indicate whether this is a major or minor source of money in the economy and whether you think it compares today vs 20 years ago vs how important it might be 20 years in the future. (Is the role of the banking system consistent over time or evolving? If evolving where is it heading, if its not evolving, why has it remained stable over time?)

While we are still far from “Transcendence” -style artificial intelligence — like uploading human consciousness to software programs, at the rate we are going in technological innovations and in terms of the convergence between our noted three worlds ( the physical world, the virtual or digital world, and our very own intellectual world “inside our brain”), we could someday digitize the human brain, and reproduce cognitive intelligence and emotions, machines and computers that can totally replace human insight.

What are the pros and cons of this technological evolution and what kind of implications would this have on an individual and our society as whole?
