A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 23.4 m/s at an angle of 48.0° to the horizontal.

(a) By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)
m
(b) Does the ball approach the crossbar while still rising or while falling?

You and your spouse have decided that now is a good time to "buy vs. own." You have found a dream house that costs 278970 and you can get an loan-to-value of 89%. Your broker has lined up a traditional, fully amortizing loan at an interest rate of 6 annual, compounded 12/year for a 30 year term. What will your mortgage payments be if you buy the house?

You have taken on a new job that will be extremely intense and not leave much time for vacations. Your significant other is willing to put up with things but wants you to promise to take them on a dream vacation at the end of the 5th year. Since you haven't been able to deliver on these promises in the past, they want you to set aside enough money to cover that cruise which will cost $13835. If you can earn 5% annual, compounded monthly, how much will you have to set aside?

You are putting together a partnership and want to bring in a partner who is very focused on building up his wealth. You have run your cash flows and think you can promise to give him a constant annual dividend of 23109. Assume he can earn 6% compounded 1 times per year on his money. He wants to know what the investment will accumulate to if you run the partnership for 8 years. What will he have accumulated in his account by then?

You are worried about the future of social security and want to start saving. You think you can set aside $1606 per month. You have been offered an investment product on which you can earn 3% annually compounded 12 times per year. How much will this accumulate to if you plan to retire at the end of the 10th year?

When a small object approaches a much more massive object, the smaller object can be tidally disrupted. The distance of the closest approach before being tidally disrupted is the Roche limit (recall lecture on rings of plan- ets). If the small object is a star and the large object is a supermassive black hole, the Roche limit is given by

rR= 2.4 * RS * (pBH/p*)^(1/3)

where RS is the Schwarzschild radius, ρ̄BH is the average density of the black hole and ρ̄∗ is the average density of the star.

1. a) Setting the average density of the supermassive black hole equal to its mass divided by the volume contained within the Schwarzschild radius, derive an expression for the mass of a black hole as a function of ρ̄∗ that would have rR = RS.

2. b) If the Sun were to fall into a supermassive black hole, what maximum mass could the black hole have if the Sun would be tidally disrupted before crossing the event horizon (or RS). Compare your answer with typical supermassive black holes in the galactic nuclei.

3. c) If the mass of the supermassive black hole exceeded the mass found above, what would be the implication in terms of the energy release of the infalling star? Could infalling stars effectively power AGNs in this case?

1）On a certain dry sunny day, a swimming pool's temperature would rise by 1.40°C if not for evaporation. What fraction of the water must evaporate to carry away precisely enough heat to keep the temperature constant?

2）A piece of iron block moves across a rough horizontal surface before coming to rest. The mass of the block is 3.3 kg, and its initial speed is 3.2 m/s. How much does the block's temperature increase, if it absorbs 74% of its initial kinetic energy as internal energy? The specific heat of iron is 452 J/(kg · °C).

1. A 25-year, 5% coupon bond, pays interest semi-annually, and is priced to yield 5%.

a. What is its approximate modified duration for 100bps change in yield?

b. What is its approximate convexity for 100bps change in yield?

c. Using its approximate modified duration alone, how much (in % terms) do you expect the price of this bond to change if interest rates increase by 200bps?

d. Using its modified duration and convexity, how much (in % terms) do you expect the price of this bond to change if interest rates increase by 200bps?

e. Compare the actual expected change in the value of the bond if yields across the yield curve increased by 200bps for this issuer vs. the answer obtained in part d above.

A load of bricks of mass M = 185 kg is attached to a crane by a cable of negligible mass and length L = 3.19 m. Initially, when the cable hangs vertically downward, the bricks are a horizontal distance D = 1.39 m from the wall where the bricks are to be placed. What is the magnitude of the horizontal force that must be applied to the load of bricks (without moving the crane) so that the bricks will rest directly above the wall?

Cumberland County Senior Services is a non-profit organization devoted to providing essential services to seniors who live in their own homes within the Cumberland County area. Three services are provided for seniors—home nursing, Meals on Wheels, and housekeeping. In the home nursing program, nurses visit seniors on a regular basis to check on their general health and to perform tests ordered by their physicians. The Meals on Wheels program delivers a hot meal once a day to each senior enrolled in the program. The housekeeping service provides weekly housecleaning and maintenance services. Data on revenue and expenses for the past year follow:

*Allocated on the basis of program revenues.

     The head administrator of Cumberland County Senior Services, Judith Ewa, is concerned about the organization’s finances and considers the operating income of $6,400 last year to be razor-thin. (Last year’s results were very similar to the results for previous years and are representative of what would be expected in the future.) She feels that the organization should be building its financial reserves at a more rapid rate in order to prepare for the next inevitable recession. After seeing the above report, Ewa asked for more information about the financial advisability of discontinuing the
housekeeping program.

     The depreciation in the housekeeping category is for a small van that is used to carry the housekeepers and their equipment from job to job. If the program were discontinued, the van would be donated to a charitable organization. Depreciation charges assume zero salvage value. None of the general administrative overhead would be avoided if the housekeeping program were dropped, but the liability insurance and the salary of the program administrator would be avoided.

Required:

1-a. Compute the change in net operating income for the company as a whole if housekeeping program be discontinued.

1-b. Should the housekeeping program be discontinued?

• Yes

• No

2. Would a segmented income statement format be more useful to management in assessing the long-run financial viability of the various services?

• Yes

• No

A 10-year-old girl was brought to an outpatient clinic because she complained of sore throat and a lump in her neck. On examination, she was observed to have a tonsillar abscess, swollen glands, and widespread bruising in the extremities. She also had a low-grade fever. She was treated with antibiotics and released, but she failed to progress over the next 2 days. Hematology laboratory tests revealed a WBC of 8.0 x 10^9/L, a hematocrit of 28%, and a platelet count of 10 x 10^12/L peripheral blood differential count revealed 3 band neutrophils, 25 segmented neutrophils, 8 lymphocytes, 1 monocyte, and 63 blasts.

The patient’s parents were contacted, and the girl was immediately admitted to the hospital. A bone marrow examination was performed and revealed an infiltration of blast cells in the marrow.

Immunophenotyping was performed on the bone marrow cells. The results show the cells have CD 11b, CD 13, CD 33, and CD15 markers.

1. Why are the hematocrit and platelet count decreased?

2. What is immunophenotyping and why is it an important test?

3. What is the most likely diagnosis based on these test results?

4. How would the results differ in the immunophenotying of the cells had CD 10, CD 19, CD 20 and CD 22 markers?
