A paratrooper steps out of an airplane at a height of 1250 ft and after 6 sec- onds opens her parachute. Her weight, with equipment, is 200 lbs.

A paratrooper steps out of an airplane at a height of 1250 ft and after 6 sec- onds opens her parachute. Her weight, with equipment, is 200 lbs. Let y(t)denote her height above the ground after t seconds. Assume that the air resis- tance is 0.005y′(t)2 lbs in free fall and 0.6y′(t)2 lbs with the chute open. At what height does the chute open? How long does it take to reach the ground? At what velocity does she hit the ground? (This model assumes that air resis- tance is proportional to the square of the velocity and that the parachute opens instantaneously.)(Hint: This problem can be solved most efficiently by using an ODE file to detect significant events. Pay attention to units. Recall that the mass of the paratrooper is 200/32, measured in lb sec2/ft. Here, 32 is the acceleration due to gravity, measured in ft/sec2.)(b) Let v = y′ be the velocity during the second phase of the fall (while the chute is open). One can view the equation of motion as an autonomous first orderODE in the velocity:v′ = 32(−1 + 0.6 v2). 20013Make a qualitative analysis of this first order equation, finding in particular the critical or equilibrium velocity. This velocity is called the terminal velocity. How does the terminal velocity compare with the velocity at the time the chute opens and with the velocity at impact?(c) Assumetheparatrooperissafeifshestrikesthegroundatavelocitywithin5% of the terminal velocity in (b). Except for the initial height, use the parameters in (a). What is the lowest height from which she may parachute safely? (Please do not try this at home!)

“A continuous electric current of 2,000 amps is to be transmitted from a generator to a transformer located 230 feet away. A copper conductor can be installed for $5.2 per pound, will have an estimated life of 22 years, and can be salvaged for $1 per pound. Power loss from the conductor will be inversely proportional to the cross-sectional area of the conductor. The power loss in one hour may be expressed as 6.76/A kilowatt, where A is the cross-sectional area of the conductor in square inches. The cost of energy is $0.0781 per kilowatt-hour, the interest rate is 9.8%, and the density of copper is 555 pounds per cubic foot. Calculate the optimum cross-sectional area of the conductor. You should assume the conductor operates 24 hours a day, 365 days per year.”

Equipment purchased at the beginning of the fiscal year for $840,000 is expected to have a useful life of 10 years, or 400,000 operating hours, and a residual value of $40,000. Compute the depreciation for the first and second years of use by each of the following methods:

a) straight-line

b) units-of-production (10,000 hours first year; 15,000 hours second year)

c) declining-balance at twice the straight-line rate

(Round the answer to the nearest dollar.)

Labor and Materials Costs” Please respond to the following:

  • Use the Internet and to research a U.S.-based company that manufactures technology products. Recommend one (1) approach that your selected company can take in order to lower the direct labor costs of technology products while remaining competitive with global markets. Provide a rationale for your recommended approach.
  • Imagine that you are a Chief Financial Officer (CFO) of a company. Recommend two (2) actions that you could take regarding the company’s supply chain to reduce manufacturing costs of direct materials.

A property owner wished to sell a small apartment building that she owned. She consulted a local real estate agent and listed her property.

A property owner wished to sell a small apartment building that she owned. She consulted a local real estate agent and listed her property. Because she was about to leave on her lengthy winter vacation, she provided the agent with authority to sell the property on her behalf of the terms of any offer received met the terms set out in the listing agreement. A prospective buyer inspected the property during the period of time that the property was listed for sale, but did not make an offer to purchase.

Before the property owner returned from her vacation, but after the agency agreement had expired, the prospective buyer returned and made an offer to purchase the property that corresponded with the terms of the listing agreement. The agent accepted the offer on behalf of the property owner.

After the purchase agreement was signed, the buyer discovered that the agency agreement had expired. He then began a legal action against the agent.

Explain the nature of the buyer’s actions and indicated how the case may be decided. Could the property owner ratify the agreement? What factors would affect the ratification?
