In February 2013, a 10,000 ton meteor entered the atmosphere near the city of Chelyabinsk, Russia. Analysis of the trajectory showed that the meteor was traveling at a speed of 17.5 km/s at an angle of 17.7o below horizontal, when it was at a height of 77.9 km. Fortunately the meteor exploded high in the atmosphere, where most of its energy was dissipated.

(a) Had the meteor not exploded, and ignoring air resistance, how long would it have taken for the meteor to hit the ground from its 77.9-km height?

(b) With the same assumptions as in part (a), how far in horizontal distance would the meteor have traveled from its initial location to when it hit the ground?

(c) Just before striking the ground, what would have been the meteor’s total velocity? (You may give your answer in either speed-angle or x,y component form.)

experiences with a school-age child whose family is at or near the poverty level. How did poverty impact their life? The chapter talks about strengths in the lives of people and families in poverty that may help them overcome the effects on a child's development and well-being. Include examples of strengths within the child and family, or relationships and resources available to them outside of the family that may have helped them overcome some of the obstacles to their success.

Comparing Income Statements and Balance Sheets of Competitors
Following are selected income statement and balance sheet data from two retailers: Abercrombie & Fitch (clothing in the high-end market) and TJX Companies (clothing retailer in the value priced market), for the fiscal year ended January 30, 2016.

(a) Express each income statement amount as a percentage of sales.

Round your answers to one decimal place (ex: 0.2345 = 23.5%)

(b) Express each balance sheet amount as a percentage of total assets.

Round your answers to one decimal place (ex: 0.2345 = 23.5%).

Which of the following statements about business models is most consistent with the computations for part (a)?

ANF's expenses as a percentage of sales are higher because it spends more on advertising than does TJX.

ANF is a high-end retailer that is able to charge high prices for its products, but bears substantial operating costs to support its "shopping experience."

ANF's profit is higher than TJX's as a percentage of sales because its sales are higher than TJX's.

ANF's gross profit is higher than TJX's because its sales volume allows it to manufacture clothes at a lower per unit cost than can TJX.

Which of the following statements about business models is most consistent with the computations for part (b)?

ANF reports lower current assets as a percentage of total assets because it pays its vendors on a more timely basis than does TJX.

ANF reports higher long-term assets as a percentage of total assets because it depreciates its long-term assets more slowly than does TJX.

ANF reports lower current assets and higher long-term assets as a percentage of total assets because it carries less inventory and has a greater capital investment in its stores than does TJX.

ANF reports lower current assets as a percentage of total assets because it is a smaller company and cannot afford the investment in inventory.

(c) Which company has a lower proportion of debt? What do the ratios tell us about relative riskiness of the two companies?

ANF has a lower proportion of debt than does TJX, which implies that ANF is less risky than TJX.

TJX has a lower proportion of debt than does ANF, which implies that TJX is less risky than ANF.

ANF has a higher proportion of debt than does TJX, which implies that ANF is less risky than TJX.

TJX has a higher proportion of debt than does ANF, which implies that TJX is less risky than ANF.

A lumber company has just taken delivery on a shipment of 10,000 2 ✕ 4 boards. Suppose that 10% of these boards (1000) are actually too green to be used in first-quality construction. Two boards are selected at random, one after the other. Let A = {the first board is green} and B = {the second board is green}.
(a) Compute P(A), P(B), and P(A ∩ B) (a tree diagram might help). (Round your answer for P(A ∩ B) to five decimal places.)

P(A) =
P(B) =
P(A ∩ B) =

Are A and B independent?
Yes, the two events are independent.No, the two events are not independent.    
(b) With A and B independent and P(A) = P(B) = 0.1, what is P(A ∩ B)?


How much difference is there between this answer and P(A ∩ B) in part (a)?
There is no difference.There is very little difference.    There is a very large difference.
For purposes of calculating P(A ∩ B), can we assume that A and B of part (a) are independent to obtain essentially the correct probability?
YesNo    
(c) Suppose the lot consists of ten boards, of which one are green. Does the assumption of independence now yield approximately the correct answer for P(A ∩ B)?
YesNo    
What is the critical difference between the situation here and that of part (a)?
The critical difference is that the population size in part (a) is small compared to the random sample of two boards.The critical difference is that the percentage of green boards is smaller in part (a).    The critical difference is that the percentage of green boards is larger in part (a).The critical difference is that the population size in part (a) is huge compared to the random sample of two boards.
When do you think that an independence assumption would be valid in obtaining an approximately correct answer to P(A ∩ B)?
This assumption would be valid when the population is much larger than the sample size.This assumption would be valid when the sample size is very large.    This assumption would be valid when there are fewer green boards in the sample.This assumption would be valid when there are more green boards in the sample.

Jarvene Corporation uses the FIFO method in its process costing system. The following data are for the most recent month of operations in one of the company’s processing departments:

The cost of beginning inventory according to the company’s costing system was $7,875 of which $4,849 was for materials and the remainder was for conversion cost. The costs added during the month amounted to $180,742. The costs per equivalent unit for the month were:

Required:

1. Compute the total cost per equivalent unit for the month.

2. Compute the equivalent units of material and conversion in the ending inventory.

3. Compute the equivalent units of material and conversion that were required to complete the beginning inventory.

4. Compute the number of units started and completed during the month.

5. Compute the cost of ending work in process inventory for materials, conversion, and in total for the month.

Wescott Company has three divisions: A, B, and C. The company has a hurdle rate of 8 percent. Selected operating data for the three divisions are as follows: Division A Division B Division C Sales revenue $ 1,300,000 $ 1,091,000 $ 1,096,000 Cost of goods sold 803,000 801,000 796,000 Miscellaneous operating expenses 73,000 61,000 62,000 Interest and taxes 57,000 50,000 50,000 Average invested assets 9,857,000 2,353,000 3,870,000 Wescott is considering an expansion project in the upcoming year that will cost $5.9 million and return $543,000 per year. The project would be implemented by only one of the three divisions. Required: 1. Compute the ROI for each division. (Do not round your intermediate calculations. Round your percentage answer to 2 decimal places, (i.e. 0.1234 should be entered as 12.34%.)) 2. Compute the residual income for each division. (Loss amounts should be indicated by a minus sign.) 3. Rank the divisions according to the ROI and residual income of each. 4-a. Compute the return on investment on the proposed expansion project. (Round your percentage answer to 2 decimal places, (i.e. 0.1234 should be entered as 12.34%.)) 4-b. Is this an acceptable project? No Yes 5. Without any additional calculations, state whether the proposed project would increase or decrease each division’s ROI. 6. Compute the new ROI and residual income for each division if the project was implemented within that division. (Loss amounts should be entered with a minus sign. Enter your ROI percentage answers to 2 decimal places, (i.e., 0.1234 should be entered as 12.34%.))
