Id Stores, a wholesaler chain of stores, has over 500 branches nationwide. Their product range is divided into six main categories i.e. Toiletries, Electronics, Food, “The Corporate World”, wearing apparel, and Toys. The following information relates to the accounting period just ended:
I. Although this varies from product range to product range but the company generally allows the dissatisfied customers a return policy of 30 days. (For Electronics this policy generally, however, is 1 year & for toys its 90 days). There is a 40% probability of 5% goods being returned in general category and 60% probability of 3% goods being returned. 3% of the Toys’ customers usually come up with the defective goods. Complaints regarding the Electronics are channelized back to the suppliers.
II. On May 2nd 2008, an employee got injured while unloading the goods in the company godowns. He later sued the company for having a lack in the safety measures for its employees, damages and other amounts mentioned in the claim is 1.5 million. According to the legal advisors it is highly probable that court may award a 500,000 compensation in total.
III. At the year end, the company had 950 laptops of a good brand each costing Rs.65,000. There was rising trend of prices in the market, which influenced the company’s sale policy and these computers were retained in stock till July 25, 2008 when market price started falling and within one week’s time declined to Rs.68,000. This situation forced the management to start selling. However, the whole stock could be sold till August 22, 2008 and fetched total sale proceeds of Rs.40.85 million.
IV. The Government announced on 5th July that the rates of taxes will be changed, and all changes shall be applied retrospectively.
V. A suit for infringement of patents, seeking damages of Rs. 2 million, was filed by a third party. SL’s legal consultant is of the opinion that an unfavourable outcome is most likely. On the basis of past experience he has advised that there is 60% probability that the amount of damages would be Rs. 1 million and 40% likelihood that the amount would be Rs. 1.5 million
VI. The Board of Directors announced on August 25th a 20% stock dividend for the year ended 30th June, 2008.
VII. Investments of the company amounting to Rs.10 million at the year end were disposed off for Rs. 6 million in response to a market crash on July 27, 2008.
VIII. A law suit for Rs.500,000 was filed. Unfavorable outcome is probable. A reasonable Estimate of Court’s award is in the range between Rs.100,000 and Rs.400,000. The company’s legal advisor believes the best estimate of potential liability is Rs.200,000.
IX. During December 2009, law suit was filed against the company claiming Rs.800, 000. In the opinion of legal advisor it is reasonably possible that damages will be awarded to the plaintiff.

Let’s consider the following situation: Imagine a 37 kg mass falling from a height h and landing on a spring, compressing it, and then being launched back upwards. If the spring has a spring constant of 179 N/m and is observed to be maximally compressed by 5 meters, determine the following: [Note: You may consider the top of the fully compressed spring to be located at y = 0 m] i The total energy contained in the system. ii The height above the ground from which the mass fell. iii The velocity with which the mass impacts the spring. iv The velocity of the mass when it’s launched back upwards. v What is the value of the mass’ maximum kinetic energy and at what point or points in its motion is it achieved? vi What is the value of the mass’ minimum kinetic energy and at what point or points in its motion is it achieved?

1.) Your friend is catching a falling basketball after it has passed through the basket. Her hands move straight down while catching the ball. Take that it takes about 0.10 s for the player to lower her hands to stop the ball. Assume the mass of the ball to be 0.60 kg, and that it has fallen a vertical distance of 1.2 m before reaching the player's hand. Determine the average force that her hands exert on the ball while catching it.

2.) On a frictionless horizontal air table, puck A (with mass 0.248kg ) is moving toward puck B (with mass 0.372kg ), which is initially at rest. After the collision, puck A has velocity 0.125m/s to the left, and puck B has velocity 0.653m/s to the right.

What was the speed vAi of puck A before the collision?

Calculate ?K, the change in the total kinetic energy of the system that occurs during the collision.

Question 1:Professor Handy measured the time in seconds required to catch a falling meter stick for 12 randomly selected students’ dominant hand and nondominant hand. The Minitab Express file contains these measurements. Professor Handy claims that the reaction time in an individual’s dominant hand is less than the reaction time in their nondominant hand. Assuming that the differences follow a normal distribution, test the claim at the 5% significance level.

Question 2:The New England Patriots. The 2017 roster of the New England Patriots, winners of the 2017 NFL Super Bowl included 12 defensive linemen and 9 offensive linemen. The Minitab Express file for this problem contains the weights in pounds of the offensive and defensive linemen. Use this data set to test the claim that the defensive linesmen weigh less that the offensive linemen at the 5% level of significance.

Question 3: Stress and weight in rats. In a study of the effects of stress on weight in rats, 71 rats were randomly assigned to either a stressful environment or a control (nonstressful) environment.

1. Adverse Oil Price Shock

At the beginning of the semester we identified falling oil prices as a potential risk factor for the global economy. The last few months the price of oil has dropped significantly for various reasons, and more recently shutdowns globally have exacerbated the problem by decreasing demand. Discuss the impact of a negative oil price shock on current account deficits, fiscal deficits and exchange rates.

A spherical raindrop falling through mist builds up mass. The mass accumlates at a rate proportional to its cross-sectional area and invers;ey proportional to its velocity, that is, dm/dt=k?r2/v, where r is the radius of the raindrop at a given time and v is the downard speed at the same time.Assuming the density P of the rain drop is a constant. Ignoring the resistance do to the fog and the air, calculate the instaneous acceleration of the raindrop as a function of v,r,P,g and k.

What is Reeby Sports worth per share? We will value the company using George
Reeby's forecasts.
The spreadsheet accompanying this solution sets out a forecast in the same
general format as Table 4.5. Historical results from 2011 to 2016 are also shown.Earnings
per share (EPS)equals return on equity (ROE) times starting book value per share
(BVPS). EPS is divided between dividends and retained earnings, depending on the
dividend payout ratio.BVPS grows as retained earnings are reinvested.
The keys to Reeby Sports’ future value and growth are profitability (ROE) and
the reinvestment of retained earnings. Retained earnings are determined by dividend
payout. The spreadsheet sets ROE at 15% for the six years from 2018 to 2022. If Reeby
Sports will lose its competitive edge by 2022, then it cannot continue earning more than
its10% cost of capital. Therefore ROE is reduced to 10%startingin 2023.1
The payout ratio is set at .30 from 2018 onwards. Notice that the long-term
growth rate, which settles inafter 2023, is ROE × ( 1 – dividend payout ratio) = .10 × (1 -
.30) = .07.
The spreadsheet allows you to vary ROE and the dividend payout ratio separately
for 2018-2022 and for 2023-2024.2But let’s start with the initial input values. To
calculate share value, we have to estimate a horizon value at H = 2022 and add its PV to
the PV of dividends from 2017 to 2022. Using the constant-growth DCF formula,
PV = 0.71 = 23.72 H .10- .07
The PV of dividends from 2017 to 2022 is $3.43 at the start of 2017, so share value is:3
6
PV = 3.43+ 23.72 = $16.82
(1.1)
The spreadsheet also calculates the PV of dividends through 2024 and the horizon
value at 2024. Notice that the PV at the start of 2017 remains at $16.82. This makes sense, since the value of a firm should not depend on the investment horizon chosen to calculate
PV. (If you calculate a value that does depend on the horizon, you have made a mistake.)
We have reduced ROE to the 10% cost of capital after 2022, assuming that Reeby
Sports will have exhausted valuable growth opportunities by that date. With PVGO = 0,
PV = EPS/r.4So we could discard the constant-growth DCF formula and just divide EPS
in 2023 by the cost of capital:
PVH = 2.37 = $23.72 .10
This PVis identical to the PV from the constant-growth DCF formula. It doesn’t matter
how fast a company grows after the horizon date H if it only earns its cost of capital.
How much of Reeby Sports’ value is due to PVGO?You can check by setting
ROE = .10 for 2018 and all later years.You should get PV = $13.82. Thus PVGO = 16.82
– 13.82 = $3.00 per share for investments made in 2017onward.
George Reeby has also identified a "comparable," Molly Sports. We could use its
P/E ratio of 13.1 to calculate horizon value in 2022 and PV at the start of 2017. Using
the original inputs for ROE, EPS in 2023 is 2.37.5
H
6
PV 13.1 2.37 $31.05
PV 3.43 31.05 $20.96
(1.10)
= ´ =
= + =
We couldalso use Molly’s P/E ratio to calculate Reeby Sports’ PV at the start of 2017
directly from 2017 EPS:
PV = 13.1 ´ 2.03 = $26.59

The Question is ?
Both values based on Molly’s P/E are higher than our DCF calculations. Is Molly
significantly more profitable than Reeby Sports, or does our spreadsheet understate
Reeby Sports’ prospects?
What if Reeby Sports could continue to earn ROE = .15 for two extra years, until
2024?You can check by changing ROE for 2023-2024 from .10 to .15. (The ROE for
2025 and 2026 is hard-wired at .10.)You should get NPV of $18.04, somewhat higher
than our original DCF calculations, but not enough for Reeby Sports to match Molly’s P/E.You may wish to experiment to find inputs that generate P/E = 13 for Reeby Sports
at the start of 2017. Do you think these inputs are reasonable?
