Design a “bungee jump” apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 15 m long, and that the cords stretch in the jump an additional 20 m for a jumper whose mass is 100 kg, the heaviest adult you will allow to use your bungee jump (heavier customers would hit the ground).(e) Which of the following statements is a valid basis for answering part (d) correctly? [Part(d) answer was the jumper’s momentum is changing]Since the net force must be zero when the momentum is zero, and since dpy/dt is equal to the net force, dpy/dt must be zero.A very short time ago the momentum was downward (and nonzero).If the momentum weren’t changing, the momentum would remain zero forever.After a very short time the momentum will be upward (and nonzero).Since the momentum is zero, the momentum isn’t changing.Check to make sure that the magnitudes of the velocity and force vectors shown in your diagram number 4 are consistent with your analysis of parts (c), (d), and (e).(f) Focus on this instant of greatest tension and, starting from a fundamental principle, determine the spring stiffness ks for each of the two cords.N/m (g) What is the maximum tension that each one of the two cords must support without breaking? (This tells you what kind of cords you need to buy.)N (h) What is the maximum acceleration |ay| = |dvy/dt| (in “g’s”) that the jumper experiences? (Note that |dpy/dt| = m|dvy/dt| if v is small compared to c.)g’s (acceleration in m/s2 divided by 9.8 m/s2)

QUESTION #1

Based on the required reading from the text and any other scholarly sources you choose to use, please outline and describe a macroeconomic approach a country could use that would maximize the aggregate demand the rest of the world’s nations have for the goods and services it produces.

QUESTION #2

A) The Trump administration has hired you to present a specific strategy for keeping America’s inflation and unemployment rates low. Please share it here.

B) After presenting the strategy a concern is voiced that if either inflation or unemployment are too low they will cause the other to rise. Explain how this can happen and how you will prevent it.

QUESTION #3

A newly formed country wants to make sure the economy it is building will successfully generate jobs and steadily rising standards of living. Based on what you have learned in this course and from any other scholarly sources, list and explain the components of a successful economy.

QUESTION #4

Go to http:// and look through the 2017 Index of Economic Freedom, where 150+ countries are ranked according to their levels of economic freedom.

A) Pick a country in the top ten of the rankings and clearly explain the primary reasons for its ranking.

B) Pick a country in the bottom ten of the rankings and clearly explain the primary reasons for its ranking.

Can someone help me figure out how to work problem in excel? I have worked out the math I just cannot figure out how to input it into excel.Input it into excel.

A metropolitan school system consists of three districts-north, south, and central. The north district contains 25% of all students, the south district contains 40%, and the central district contains 35%. A minimum-competency test was given to all students; 10% of the north district students failed, 15% of the south district students failed, and 5% of the central students failed.

b. Develop a joint probability table.

c. What is the probability that a student selected at random failed the test?

On January 15, a farmer knows that he/she will have to sell 40,000 bushels of corn in 6 months’ time. The farmer is worried that the price of corn is going to decrease in the next 6 months and takes a short position in 80 September corn futures contracts. The futures price is £20 per bushel on January 15. Each futures contract is for the delivery of 500 bushels of corn. On July 15, the farmer sells the 40,000 bushels of corn at the spot price and closes the futures position with an offsetting transaction. At the expiration of the hedge (July 15), the spot price of corn is £25 per bushel and the futures price is £26 per bushel. What are the total proceeds from the sale of the 40,000 bushels of corn? Consider the gains or losses from the futures contracts when computing the total proceeds. Is the price per bushel realised by the farmer equal to the futures price at which he/she entered into the futures position on January 15? If it is not equal, explain why the price per bushel is different from the initial futures price.
