You are a consultant to a large manufacturing corporation considering a project with the following net after-tax cash flows (in millions of dollars): Years from Now After-Tax CF 0 –36 1–9 12 10 24 The project's beta is 1.5. Assuming rf = 4% and E(rM) = 12% a. What is the net present value of the project? (Do not round intermediate calculations. Enter your answer in millions rounded to 2 decimal places.) Net present value million b. What is the highest possible beta estimate for the project before its NPV becomes negative? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Highest possible beta value

A 5.80 x 103 kg delivery truck moving with a velocity of 20 m/s hits a 1.50 x103 kg parked car. As a result of the impact, the car was set in motion at 31.8 m/s. (Assume the car –truck to be an isolated system) (a) Sketch the situation. (b) Find the velocity of the truck immediately after the collision; (c) Find the kinetic energy of the car-truck system before and after the collision. (d) Is the car-truck collision elastic or inelastic? Explain (e) What is the change in momentum of the car? Assuming the collision time to be 2 seconds, how much average impact force did the car experience? (f)What is the change in the momentum of the truck? Solve for the impact force experienced by the truck.

suppose that companies located in Italy can produce 40,000 ton of Spaghetti Noodles for each year of labor they employ and, also using a year of labor, can produce 4 units of machinery. Suppose companies in Japan produce, with the same amount of labor 30,000 ton of Spaghetti Noodles and 6 units of machinery.

1. Which trade theory can best demonstrate the benefits of trade in this example and explain?
2. Explain whether each county can specialize in production of one product or not and determine which product to specialize.

c. Illustrate the amount of total production and consumption (combined both countries) before and after specialization and production, suppose that the total production after specialization will be divided equally between the two countries for consumption

Answer all parts. Write big, clear and legibly.  

A 0.10kg dart is fired horizontally at the center of a 0.80kg vertically hanging block, sticking to it. The system reaches a maximum height, h, of 0.20m above the collision point.

Find:

a) the velocity of the dart – block system just after the collision

b) the velocity of the dart before collision

c) the energy lost during the collision.

d) if the dart gains its speed due to a spring system that is initially compressed 0.05m from its equilibrium

position, determine the spring constant.

e) If the dart didn’t stick to

the block, but instead fell vertically after collision, would the initial velocity of the

dart have to be greater, less than, or equal to the velocity that was found in part (b)? Justify.

a block of mass 2.4 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 490N/m the angle of the ramp with respect to the horizontal is 31 degrees

A.) the block starting from rest slides down the ramp a distance 78 cm before hitting the spring how far in cm is the spring compressed as the block comes to momentary rest?

B.) After the block comes to rest the spring pushes the block back up the ramp how fast in meters per second is the block moving right after it comes off the spring

C.) what is the change of the gravitational potential energy in joules between the original position of the block at the top of the ramp and the position of the block when spring is fully compressed?

Interest Rate Tax

Consider a two-period economy, where the consumers can lend or borrow and the income of the consumers in both periods is exogenous. Suppose the government introduces a tax on the interest earnings of the lenders. That is, while borrowers face a real interest rate of r before and after the tax is introduced, lenders face a real interest rate of (1 − x)r, where x is the tax rate, after the tax is introduced.

1. Show the effects of the increase in the tax rate on consumer’s lifetime budget constraint.

2. How does the tax affect the optimal choices (consumption in current and future periods and saving)? Show how income and substitution effects matter for your answer, and how it matters whether the consumer is initially a borrower or a lender

Brad Johnson (BJ) is a 54-year-old diagnosed with pituitary adenoma He undergoes a transsphenoidal hypophysectomy to remove the tumor.

1. Before surgery, what conditions might BJ’s pituitary adenoma precipitated?

2. After surgery, he has huge urinary outputs of 500 to 600 ml/hr. What is the most likely cause of his high urine output? What other clinical data would support this diagnosis?

3. BJ receives subcutaneous Desmopressin (DDAVP) to manage his high urine output. What is the rationale for this therapy? How can effectiveness be assessed?

4. It is expected that after his transsphenoidal hypophysectomy, all of BJ’s anterior pituitary hormones will be deficient (panhypopituitarism). What type of hormone replacement will be needed?
