In this problem, we will consider the following situation as depicted in the diagram: A block of mass m slides at a speed v along a horizontal, smooth table. It next slides down a smooth ramp, descending a height h, and then slides along a horizontal rough floor, stopping eventually. Assume that the block slides slowly enough so that it does not lose contact with the supporting surfaces (table, ramp, or floor). You will analyze the motion of the block at different moments using the law of conservation of energy.
Part A
Which word in the statement of this problem allows you to assume that the table is frictionless?
Part B
Suppose the potential energy of the block at the table is given by mgh/3. This implies that the chosen zero level of potential energy is __________.
Part C
If the zero level is a distance 2h/3 above the floor, what is the potential energy of the block on the floor?
Express your answer in terms of some or all the variables m, v, h and and any appropriate constants.
Part D
Considering that the potential energy of the block at the table is mgh/3 and that on the floor is -2mgh/3, what is the change in potential energy ΔU of the block if it is moved
from the table to the floor?
Part E
Which form of the law of conservation of energy describes the motion of the block when it slides from the top of the table to the bottom of the ramp?
Part F
As the block slides down the ramp, what happens to its kinetic energy K, potential energy U, and total mechanical energy E?
Part G
Using conservation of energy, find the speed vb of the block at the bottom of the ramp.
Express your answer in terms of some or all the variables m, v, h and and any appropriate constants.
Part H
Which form of the law of conservation of energy describes the motion of the block as it slides on the floor from the bottom of the ramp to the moment it stops?
Part I
As the block slides across the floor, what happens to its kinetic energy K, potential energy U, and total mechanical energy E?
Part J
What force is responsible for the decrease in the mechanical energy of the block?
Part K
Find the amount of energy E dissipated by friction by the time the block stops.
Express your answer in terms of some or all the variables m, v, h and and any appropriate constants.

Capsim is a simulation of a business and gives the person the possibility to run a business as a manager before the actual business becomes into effect. During the simulation a person takes responsibility of a business and run the company as a manager. In addition, it gives the person the ability to see what a person can do better in order for their business to compete and be better with competitors. Different things I had learned from business capsim. Some of them are Production, right marketing, research, and one of the most important one, finances.
Marketing is very important aspect of capsim. Marking is used to advertise the product that the business will be selling. For example, some people create web pages, rent billboard, and use social media to reach out to people in the community. Marketing is the main way how a business will reach to their customers. Customers would respond back base on the proper marketing in the community. In addition, the production and marketing would go together. When the business is advertising their product, the business has to assured that the business is providing what it is being advertised Many times, word of mouth will be another way to reach client. Which it goes back to the production of the business, the customer is expecting to be blown out by the business. If that is achieved that customer is likely to referred the business to someone else. It is important to make the right impression on the first time.
Another important part is research. Research will help reach customers that are not being reached with billboard or advertisement. Research can be complete over social media, such as, Twitter, Instantgram , snapchat, facebook or other platform. Additionally, people are willing to try new places as long as they find the place is worth and the prices are right for them. I feel that research can help the business reach those goals and sustained them.
Finally, finances, which I feel is the most important of all. Finance is the center of the business. Without the proper capital the business can suffer and decline and missed clientele that could be reach. The reason I believe finances is the most important of all, if the business has money to spend, the business can make progress. The business can utilize money to do marketing and research in order to reach the proper client.
Responding to the comment above by my classmate. Response should be at least 200 words.

Individuals experience various mood states or emotions at varying times every day, both subtle changes and obvious changes, that can result in attitude alternations with both negative and positive effects and impair or facilitate performance. The connections in the brain between emotion and memory have been particularly interesting to researchers given that neural networks that are activated by mood states are linked with neural networks that process basic perceptual functions such as word processing. Dr. Siebert has conducted a number of research experiments inducing various mood states through the use of music and then studying the effects of mood on lexical processing. (Dr. Pennie S. Siebert) Research suggests that an individual’s mood state or emotion influences cognition and memory, but to investigate the influence of mood on cognition and memory, researchers must first be able to induce mood states in their research participants. One strategy for inducing mood is through the use of various types of music. To assess the effectiveness of mood induction, researchers divided participants into two groups and had them listen to a set of songs which had independently been rated as upbeat and cheerful (to induce happiness) or a set of songs that had been rated as somber and mournful (to induce sadness). After listening to the music (happy or sad), participants were asked to complete a self-evaluation of their mood by drawing an X to represent their position on a line with happy at one end and sad at the other. Lines were then measured in distance from the sad end of the scale, creating a mood score wherein higher scores indicated happier mood and lower scores indicate a sad mood. Research Question: Is there a difference in mood between subjects who listen to happy music versus sad music? Sad: 1.20, 3.20, 2.10, 2.10, 4.90 Happy: 5.20, 6.10, 4.10, 4.10, 5.80 1. Write null and alternative hypotheses (in words and notation) appropriate for this research scenario. 2. Compute an independent samples t-test to test the hypotheses, use an α = .05, two-tailed. Clearly describe the independent and dependent variables. How do you identify M1 and M2? 3. Calculate r2 measure of effect size and 95% confidence interval. 4. Write a results paragraph that interprets and explains the results of your test.

John Hoke owns Hoke’s Spokes, a bicycle shop. Most of John’s bicycle sales are customer orders. However, he also stocks bicycles for walk-in customers. He stocks three types of bicycles: 1) road bike, 2) e-bike and 3) mountain bike. From his overseas supplier, the cost to obtain each type of bike are: road bike $1,200, e-bike $1,700 and mountain bike $900. He sells road bikes for $1,800, e-bikes for $2,100 and mountain bikes for $1,200. His profit is the difference between sales price and cost. He has $12,000 available this month to import bikes. Each bike must be assembled; a road bike requires 8 hours to assemble, an e-bike requires 12 hours and a mountain bike requires 16 hours. He estimates that he and his employees have 120 hours available to assemble bikes. He has enough display space in his store for 20 bikes this month. Based on past sales, John wants to stock at least twice as many mountain bikes as the other two combined because mountain bikes sell better.
(a) Formulate a linear programming model for this problem and write it down in the space here:
(b) Solve the linear programming model formulated in (a) using “solver” tool in Excel, making sure to request an answer report and a sensitivity report (attach these reports to the Word file). What is the optimal number of each type of bike to import? Road bike ____ e-bike ____ Mountain bike _____
(c) Should John Hoke try to increase his budget for purchasing bikes, or is it better for him to rent extra space to stock more bikes or is it better to increase labour hours to assemble bikes? Why? John is better to increase the assembly hours he has available
(d) By how much would the profit margin (in $) have to rise on an e-bike before it would be optimal to include at least one e-bike in John’s import order? Explain your answer.
(e) Suppose that John’s employees went on strike and demand an increase of $5 per hour. Can he afford to pay them? Explain your answer.

A study was conducted to investigate the concentration of hydrophobic organic substances such as Aldrin in the Wolf River in Tennessee. Aldrin concertation measurements (in nanograms per litre) were taken downstream of an abandoned dump site that had previously been used by the pesticide industry to dispose of its waste products. It was expected that Aldrin concentration might have a nonhomogeneous vertical distribution in the river because of differences in density between these compounds and water and because of the adsorption of these compounds on sediments, which could lead to higher concentrations on the bottom. As a results water samples from surface, mid depth and bottom of the river were collected at random and measured for Aldrin concentration.The following data were obtained:
| Surface | Mid-depth | Bottom |
| 3.08 | 5.17 | 4.81 |
| 3.58 | 6.17 | 5.71 |
| 3.61 | 6.26 | 4.9 |

Case Study
B.R Investments is a reputed finance company having 15 branches in different part of the country. In the home office there are more than 200 employees. This company has a performance rating under which the employees are rated at six months intervals by a committee of two executives. Graphic scales have been used as means of appraisal. The qualities considered are responsibility, initiative, and interest in work, leadership potential, co-operative attitude and community activity. After the performance is evaluated, the ratings are discussed with the concerned employees by their immediate boss who counsels them. The ratings aroused to influence promotions and salary adjustments the employees and also as a criterion for assigning further rating for them.
Recently three employees of the company called on the company’s president to express their dissatisfaction with the ratings they had received. Their scores and composite ratings had been discussed with them. Because their ratings were comparatively low, they had been denied annual increments in salary. Approximately, two thirds of all the employees received such increments. The aggrieved employees argued that their ratings did not accurately represent their qualifications or performance. They insisted that “community activity” was not actually a part of their job and that what they do off the job is none of the company’s business. They expressed their opinion that employees should organize union and insist that salary increase be automatic.
The threat of a union caused concern to the officers of the company. This particular experience convinced the top officers that ratings may represent a serious hazard to satisfactory relationship with employees. Even the chief executive finds that performance appraisal is a dangerous source of friction and its hazards outweigh its values; so it should be discontinued altogether.
Questions:
1. How far do you agree with the management that performance appraisal should be discontinued?
2. If you were the HR manager, how would you tackle the situation?
3. What modifications would you suggest in the performance appraisal system of the company?
