A professional boxer hits his opponent with a 1345-N horizontal blow that lasts for 0.122 s.

a) Calculate the impulse (in kg · m/s) imparted by this blow.

b) What is the opponent's final velocity (in m/s), if his mass is 113 kg and he is motionless in midair when struck near his center of mass?

c) Calculate the recoil velocity (in m/s) of the opponent's 11.4 kg head if hit in this manner, assuming the head does not initially transfer significant momentum to the boxer's body.

Part 1: Pricing Strategy

Briefly describe pricing for your product or service for non for profit youth program. How does this compare to competitors, assuming competitors are at or near break-even point with their pricing? Analyze pricing alternatives and make recommendations about pricing going forward based on the following:

• How sensitive are your customers to changes in price?
• What revenue do you need to break even and achieve profitability?

• What does the price say about your product in terms of value, quality, prestige, etc.?

Businesses hold inventories of goods, partly as finished products and partly as goods-in-process and raw materials. Suppose that we think of inventories as a type of capital, which enters into the production function. Then changes in these stocks represent investment in inventories. (Typically, economists assume that the rate of depreciation on inventories is near zero.)

1. How does an increase in the real interest rate affect the quantity of inventories that businesses want to hold? What happens, therefore, to inventory investment?

2. Consider temporary adverse shock to the production function. What happens to the amount of inventory investment?

CRITICAL THINKING:

1) Patricia knows that if her 3-year-old, Emma, comes down with the flu this winter, it’s likely that the entire household will get sick. Last year, Emma got sick and sneezed and wiped her nose on whatever was near her, including her baby brother, and wanted to be held when she felt feverish. What’s the reason for the spread of the flu in Patricia’s house?

2) Why is it necessary for an allied health professional to be extremely careful when handling and transporting microbiologic specimens?

Airnova Inc. is considering four different types of stocks. They each have a required return of 20 percent and a dividend of $3.75 for share. Stocks, A, B, and C are expected to maintain constant growth rates in dividends for the near future of 10 percent, 0 percent, and -5 percent, respectively. Stock D is a growth stock and will increase its dividend by 30 percent for the next four years and then maintain a constant 12 percent growth rate after that. Please answer with the formula used.

What is the dividend yield for each of the four stocks?
