A diver springs upward from a board that is 3.02 meters above the water. At the instant she contacts the water her speed is 9.15 m/s and her body makes an angle of 77.2° with respect to the horizontal surface of the water. Determine her initial velocity.

1) Explain Adam Smith statement that : "nothing is more useful than water: but it will purchase scarcely anything; scarcely anything can be had in exchange for it." Use the Diamond-Water paradox as an example.? Do you think Adam Smith statement still holds true today? Which drivers make water a scarce resource today? Do you think management of water will be a challenging issue in Saudi Arabia within the next few decades?

In the game of Lucky Sevens, the player rolls a pair of dice. If the dots add up to 7, the player wins $4; otherwise, the player loses $1. Suppose that, to entice the gullible, a casino tells players that there are many ways to win: (1, 6), (2, 5), and soon. A little mathematical analysis reveals that there are not enough ways to win to make the game worthwhile; however, because many people's eyes glaze over at the first mention of mathematics “wins $4”.

      Your challenge is to write a program that demonstrates the futility of playing the game. Your Python program should take as input the amount of money that the player wants to put into the pot, and play the game until the pot is empty.

            The program should have at least TWO functions (Input validation and Sum of the dots of user’s two dice). Like the program 1, your code should be user-friendly and able to handle all possible user input. The game should be able to allow a user to ply as many times as she/he wants.

            The program should print a table as following:

      Number of rolls            Win or Loss                 Current value of the pot

                  1                                 Put                                    $10

                  2                                 Win                                  $14

                  3                                 Loss                                  $11

                  4

                  ##                              Loss                                  $0

        You lost your money after ## rolls of play.

        The maximum amount of money in the pot during the playing is $##.

        Do you want to play again?

      At that point the player’s pot is empty (the Current value of the pot is zero), the program should display the number of rolls it took to break the player, as well as maximum amount of money in the pot during the playing.

        Again, add good comments to your program.

        Test your program with $5, $10 and $20.

Your company is trying to decide between the following three projects. In your calculations, assume a 6% interest rate. Project A Project B Project C Project A has $400 in upfront costs in year 0 and gets 250 in benefits in year 0. It accrues $300 in benefits each year in years 1-3, and has annual costs of $200 in years 1-3. Project B costs $1300 in year 0 and has no benefits in year 0. It accrues $650 in benefits each year in years 1-3. Annual costs in years 1-3 are $450. Project C has $1000 in upfront benefits and 1600 in costs in year 0. It accrues 600 in benefits in years 1-3 and 350 in costs in years 1-3. Time value of money. Using the discounting techniques we learned in class (assume an interest rate of 6%), appropriately discount the costs and benefits of the three projects. Which project will have a higher return on investment? Be sure to show your work (10 pts). Which project achieves payback faster? (5 pts)?

PROBLEM # 4:

You are considering investing $300,000 in an activity which will generate a yearly income of $25,000 for the first 5 year, thereafter the income will increase by $7,000 per year for the following 10 years, when the life of the investment will end. You know that the ongoing money market interest rate is 5%.

1. Should you proceed with the investment? (show the equation)
2. Plot the NPW of the investment for i= 3%, 5%, 7%, 8%, 9%, 10% . At what point does the investment becomes unattractive?

PROGRAM DESCRIPTION: In this assignment, you will read an unspecified number of lines of text from STDIN. Input is terminated with EOF (ctrl-d for keyboard input). Your only output, to STDOUT, will echo the input except that the letters of any word with more than three characters will be randomly shuffled (except for the first and last letters). Don't scramble any punctuation, and you may assume that punctuation will only occur at the end of a word. Any word will have, at most, one punctuation character. Punctuation does not count towards the length of the word. You may also assume that each word will be separated by one space and that a line will have no leading or trailing whitespace. Blank lines are allowable. You must preserve the newlines (output must have the same number of lines and the same number of words on each line as when input.) (A word, here, is defined as a sequence of alphanumeric characters delimeted by whitespace.) For this assignment you must code the shuffle algorithm as described in class, and not a library shuffle function.

Sample input:According to research at an English university, it does not matter in what order the letters in a word are, the only important thing is that the first and last letter are in the right place. The rest can be a total mess and you can still read it without a problem. This is because we do not read every letter by itself but the word as a whole and the brain figures it out anyway.

Sample run:

This is a test
This is a tset
Hello, how are you today?
Hlleo, how are you toady?

SUGGESTIONS

You may find it easiest to complete this program in stages. Begin by writing a program that echos input lines of text to output. Then add the ability (a function) to break a line of text into individual words, finally add the scrambling feature (another function) for a word.

Suppose you heard the following criticism of social psychological research: “A lot of the studies are done with college students in artificial laboratory settings, such as the Latané and Darley experiment in which people heard another student have a seizure while wearing headphones in a cubicle.

1. What is the value in studies like this (given that the participants are not representative samples of ALL human beings)? What do we need to watch out for when we are interpreting the results?  

2. Can we learn anything from studies in which the settings are not representative of everyday life?

3. How would a social psychologist answer this criticism?

For many years, Thomson Company manufactured a single product called LEC 40. Then three years ago, the company automated a portion of its plant and at the same time introduced a second product called LEC 90 that has become increasingly popular. The LEC 90 is a more complex product, requiring 0.80 hours of direct labor time per unit to manufacture and extensive machining in the automated portion of the plant. The LEC 40 requires only 0.40 hours of direct labor time per unit and only a small amount of machining. Manufacturing overhead costs are currently assigned to products on the basis of direct labor-hours. Despite the growing popularity of the company’s new LEC 90, profits have been declining steadily. Management is beginning to believe that there may be a problem with the company’s costing system. Direct material and direct labor costs per unit are as follows: LEC 40 LEC 90 Direct materials $ 30.00 $ 50.00 Direct labor (0.40 hours and 0.80 hours @ $15.00 per hour) $ 6.00 $ 12.00 Management estimates that the company will incur $912,000 in manufacturing overhead costs during the current year and 60,000 units of the LEC 40 and 20,000 units of the LEC 90 will be produced and sold. 1-a. compute the predetermined overhead rate assuming that the company continues to apply manufacturing overhead cost on the basis of direct labor hours. 1-b. using this rate and other data from the problem, determine the unit product cost of each product. 2. management is considering using activity-based costing to assign manufacturing overhead cost to products. The activity-based costing systemm would have all following four activity cost pools: Activity Cost Pool Activity Measure Estimated Overhead Cost Maintaining parts inventory Number of part types $ 225,000 Processing purchase orders Number of purchase orders 182,000 Quality control Number of tests run 45,000 Machine-related Machine-hours 460,000 $ 912,000 Expected Activity Activity Measure LEC 40 LEC 90 Total Number of part types 600 900 1,500 Number of purchase orders 2,000 800 2,800 Number of tests run 500 1,750 2,250 Machine-hours 1,600 8,400 10,000 Determine the activity rate for each of the four activity cost pools. 3. using the activity rates you computed in part 2 a. determine the per unit amount of manufacturing overhead cost that would be assigned to each product using the activity based costing system,. b. compute the unit product cost of each product
