2.(a) Ball A is released from rest. It collides with the stationary ball B with a velocity 3.2 m/s; immediately after the collision ball A travels in the same direction with velocity 2.3 m/s.   

Ball A has mass 0.26 kg; ball B has mass 0.07 kg.

Calculate

(i) the velocity of ball B immediately after the collision..

(ii) the maximum height reached by ball B.

(b) A driver is travelling at a constant speed of 15.4 m/s in a 1800 kg car.

At this speed he then enters a large empty car park, and makes a U-turn, travelling in a complete half-circle of radius r.

The friction force between the tyres and the ground is 12.4 kN.

Calculate r.

The Japanese harvester beetle has infected several forests in the Northwest. Official estimates are that 17% of trees are infected. You are a park ranger who has been seeing a lot of these beetles lately, and you think the rate is higher in your area. You check 400 trees around your cabin and find that 79 of them are infected.

• Go through the steps on the Hypothesis Test Guide (D2L). List each step like Step 1, Step 2, etc.
• Please check the conditions using complete sentences.
• Please do the calculations out the long way, but definitely use GeoGebra or a calculator stats package to check.
• Even if the conditions aren’t met, do the rest anyway.
• Use α = 0.03

Write a creative story to tell about the journey of a jogger from one location in a park to another location. Make up some events and experiences that the jogger goes through on his/her journey. Tell what happens to the jogger throughout the journey (e.g., being chased by a dog or having to slow down for a parade, etc.) As you tell the story, use the terms speed, velocity and acceleration and explain how and why these values change for the jogger as he/she goes through different parts of his/her trip. Your story can be creative and funny or serious as long as you use the terms speed, velocity and acceleration. Make sure that the story conveys the meanings of these terms and the differences between them.

At the Doha Zoo, access to the public is organized as follows:

There are five employees at the entrance who sell entry passes to everyone who is not subscribed and be allowed to enter,

As for subscribers, they only display the membership card on entry. At the end of the day, one of the employees delivers cash to the cashier, the treasurer counts the cash received and places the cash in the designated treasury.

At the end of the week, the cashier deposits the cash in the bank according to the deposit slip. The deposit slip is used in the journal Cash Receipts,

Also, the treasurer is the one who certifies the payment of garden expenses and is the one who pays the expenses.

The park administration discovered the need to improve the internal control system of the cash receipts system

What are the weaknesses? What are the appropriate procedures to overcome the system's weaknesses?

Melissa recently paid $625 for round-trip airfare to San Francisco to attend a business conference for three days.

Enter zero if applicable.) (Round your answer to the nearest dollar amount.)

a. What amount of the travel costs can Melissa deduct as business expenses?

b. Suppose that while Melissa was on the coast, she also spent two days sightseeing the national parks in the area.

1. Airbnb has housed over 150 million guests in over 65,000 cities since 2008. Do a bit of research on what Airbnb is and how cities and the hotel industry has been responding to it. Draw a supply and demand graph, model the labor market for hotel workers, pre-Airbnb, and show how Airbnb has likely affected the market.

2. We all love to go to little, local ice cream shops. Many of these places hire teenagers over the summer to serve these delicious treats for us. Suppose that a new minimum wage bill comes online this summer, raising the minimum to $10/hour. Create two graphs: 1) model the market for these ice cream shop workers and how shop owners will likely respond to the minimum wage increase immediately after it happens; 2) model what would happen if a company starts using very cheap robot ice cream servers... how does it affect the market for teenage servers. Explain in your paragraph what is going on and give arguments why your graph is reasonable.

3. Many parts of the U.S. have a shortage of IT workers... not enough people are trained in these fields. Model the market for IT workers. What would happen if a new training program was targeted toward people in Appalachia who have a hard time finding work... the program trains this group to be IT technicians. Does it lead to more employment in IT?

4. You are looking at the labor market for young, childless males seeking work with low-paying employers (i.e. Wal-Mart). With a supply and demand graph, show the effects of expanding the EITC to these workers. Illustrate an initial equilibrium (before EITC), the shift due to the new EITC expansion, and point out the wage they get paid from the employer and the additional “pay” they get due to the EITC.

In a murder trial in Los Angeles, the prosecution claims that the defendant was cut on the left middle finger at the murder scene, but the defendant claims the cut occurred in Chicago, the day after the murders had been committed. Because the defendant is a sports celebrity, many people noticed him before he reached Chicago. Twenty-two people saw him casually, one person on the plane to Chicago carefully studied his hands looking for a championship ring, and another person stood with him as he signed autographs and drove him from the airport to the hotel. None of these 24 people saw a cut on the defendant’s finger. If in fact he was not cut at all, it would be extremely unlikely that he left blood at the murder scene.

(a) Because a person casually meeting the defendant would not be looking for a cut, assume that the probability is 0.7 that such a person would not have seen the cut, even if it was there. Furthermore, assume that the person who carefully looked at the defendant’s hands had a 0.4 probability of not seeing the cut even if it was there and that the person who drove the defendant from the airport to the hotel had a 0.6 probability of not seeing the cut even if it was there. Given these assumptions, and also assuming that all 24 people looked at the defendant independently of each other, what is the probability that none of the 24 people would have seen the cut, even if it was there? (Do not round intermediate calculations and round your final answer to 4 decimal places.)

Probability          

(b) What is the probability that at least one of the 24 people would have seen the cut if it was there? (Round your answer to 4 decimal places.)

Probability         

(c) Given the result of part b and given the fact that none of the 24 people saw a cut, do you think the defendant had a cut on his hand before he reached Chicago?

Yes or No

Kim is a 27-year-old woman who recently moved from a small

town in Texas to work in the city of Dallas as a reporter for one

of the major newspapers. She is 5’6” tall and weighs 115 lb. To

keep in shape she likes to jog, which she did regularly in her

hometown. She doesn’t know anyone in Dallas and has been

lonely for her family since arriving. But she has moved into a

small apartment in a quiet neighborhood and hopes to meet

young people soon though her work and church.

On the first Saturday morning after she moved into her new

apartment, Kim decided to get up early and go jogging. It was

still dark out, but Kim was not afraid. She had been jogging

alone in the dark many times in her hometown. She donned her

jogging clothes and headed down the quiet street toward a nearby

park. As she entered the park, an individual came out from a

dense clump of bushes, put a knife to her throat, and ordered her

to the ground. She was raped and beaten unconscious. She

remained in that condition until sunrise when she was found by

another jogger who called emergency services, and Kim was

taken to the nearest emergency department. Upon regaining

consciousness, Kim was hysterical, but a sexual assault nurse

examiner (SANE) was called to the scene, and Kim was assigned

to a quiet area of the hospital, where the post-rape examination

was initiated.

Answer the following questions related to Kim:

1. What are the initial nursing interventions for Kim?

2. What treatments must the nurse ensure that Kim is aware

are available for her?

3. What nursing diagnosis would the nurse expect to focus on

with Kim in follow-up care?
