1.Scenario:
A chair with a mass of 20.0 kg is attached to one end of a frictionless pulley system via a
...
a strong massless rope. The other end of the rope is attached to a steel water tank sitting on a flat horizontal concrete surface (see the image to the right). The coefficient of static friction between steel and concrete is 0.45 and the coefficient of kinetic friction between the surfaces is 0.30. The water tank, which is full of water, has sprung a leak. The combined mass of the water and the tank is 500 kg. This mass slowly decreases as the water leaks from the hole. You (i.e. your entire mass) are sitting at rest in the seat. You and the seat will remain at rest as long as the force of static friction is strong enough to hold you.
Task:
LET [DOWN] and [RIGHT] be positive. Using your knowledge of physics, determine the following:
Draw the FBD of the system of you and the chair while at rest. Using the LET statement above, write out the net force equation. [2]
Draw the FBD of the system of the water tank at rest on the flat horizontal surface. Using the LET statement above, write out the net force equations for both the vertical and horizontal planes. [3]
Using the net force equations, determine the minimum mass of water that must be lost (i.e. leaked out) from the water tank in order for you and the seat to begin falling? [4]
As soon as the chair begins to move, static friction between the steel tank and concrete surface becomes kinetic friction. Determine the magnitude of the kinetic friction. [3]
Using Newton’s 2nd law, determine the acceleration of the system at the instant that the static friction becomes kinetic friction. [6]

3.This first part of the Individual Research Project is an Outline and Annotated Bibliography. The
Outline should provide a very brief
...
tline should provide a very brief overview of what you think you will do in the Policy Brief.
The Annotated Bibliography requires you to summarize at least three peer-reviewed scholarly
sources you will cite in the Policy Brief.
This assignment is designed to get you thinking about your topic in a way that clearly anticipates
the writing you will do for the Policy Brief. We want you to brainstorm and do a bit of research
well in advance of the deadline for the Policy Brief and, most importantly, we want you to put
your ideas down on paper so that we can give you feedback before writing the actual Policy
Brief. In other words, we are asking you to submit an Outline and Annotated Bibliography so
that we can help you write the best Policy Brief possible.
Your Outline should be divided into the following five sections and should be written in
complete sentences:
I. Audience: Identify the audience you are addressing and consider what that audience
is interested in. Who are you talking to in the Policy Brief and what does this suggest
about the approach you should take? (75-100 words).
II. Problem: State how you know the issue exists. What is the proof that students need
to improve this skill? (125-150 words).
III. Importance of Problem: Indicate why this problem matters. What are the
consequences of the problem not being addressed? Why do students need to improve
this skill? (100 words)
IV. Solution: Identify your preferred solution. What solution will work in your context
and why? (75-100 words)
V. Alternative Solution: Identify at least one other possible solution. What other
solutions did you consider? (75-100 words)
The total length of the Outline should be between 450 and 550 words.
When you submit your Outline, you must also include an Annotated Bibliography. An Annotated
Bibliography is an alphabetical list of research sources that provides bibliographical data (the
title, author, date, publisher, etc.) and a short summary or annotation of the source.
Your Annotated Bibliography should contain a minimum of three scholarly or peer-reviewed
sources, each with an accompanying annotation that is between 150 and 250 words long. The
annotations must summarize the research question or thesis, research methodology, results, and
conclusion. Annotations must include summaries and paraphrased information, NOT quotations.
A good annotation will include two separate paragraphs: 1) a paragraph summarizing the
research question or thesis, research methodology, results and conclusion; and 2) a paragraph
commenting on why this source is relevant for your research.

4.ssay 1: Person I Admire
Purpose
This essay assignment is the culmination of all your previous work in this module. You have
...
in this module. You have already engaged in the beginnings of the writing process of this essay. You have:
Brainstormed ideas (see Chapter 11 in SMG) about the essay in the Discussion Board.
Condensed your ideas down into manageable points around a working thesis.
Displayed knowledge of Description essays from Learning Activities
Drafted a Writing Activity (WA2) about this Description essay.
Consulted with a writing tutor to find areas of strength and areas of improvement.
Finally, you will now compose the final draft of a description essay that:
contains a clear thesis
identifies clear points to support your thesis
engages in critical thought about the subject chosen
uses 2-4 main ideas (points) that support your overall essay thesis
allows you to expand on your chosen topic
This essay assignment represents the first steps in writing any written essay for any academic course. The idea of thesis and support are the cornerstones of all essays. They represent the last part of the writing process. However, you may still revise your essay before final submission. This form of essay writing is the basis for all other academic writing pursuits. This skill translates to almost all careers that require critical thinking, critical reading, and responding in writing. Practicing "how to" write an essay carries over into any field's task of "what" you need to write. This skill will help with all formal writing.
Task
Write a 900-word essay, in MLA format, about a person or fictional character in whom you have an interest.
Select a subject (person or fictional character you admire)
Look to your Discussion (D1) and Writing Activity 2 (WA2) for your subject
The person may be current or historical
Some fictional characters have positive traits that can be identified.
Select several (2-4) traits about the person or character that you admire and write about these. These will be the essay's main ideas.
Biographical information should be used only to support claims.
Your essay should focus on the traits you admire. Do not write a biography or tell a story.
Example of what not to do: This person was born in 1979. They were born in middle Tennessee. They went to elementary school is 1985. They graduated in 1998.
Instead, follow this example: This person was born in middle Tennessee. Entering elementary in school in 1985 was hard for them. They never felt that they belonged in kindergarten. However, they persevered, learning that school was a place for them to grow and be themselves.
Focus on the "why" you admire them instead of a list of traits. In the above example, perseverance and learning to be themselves are the traits the writer of the essay admires.
Organize your main ideas to establish the essay's pattern of organization.
Your main ideas (traits you have chosen) need to be clearly organized.
Decide in what order you wish to discuss these main ideas (traits)
This organization needs to be presented in your introduction, preferably as the last sentence of your introduction in the thesis statement.
Note: your thesis is generally the last sentence in your introduction, but it not a requirement.
Follow this structure throughout the rest of the essay.
Always check to see if your main ideas/topic sentences, in each paragraph, relate back to your thesis statement.
Compose 5 well-developed paragraphs that support a clear thesis statement that is arguable.
5 paragraph minimum
introduction paragraph
introduces your essay and presents your thesis
three body paragraphs
Each paragraph contains one of your chosen admirable traits about your subject
expressed in a topic sentence in your paragraph
Each trait needs to transition to the next one in the next paragraph
look to your chosen pattern of development
conclusion paragraph
rephrases your traits into one last paragraph
reflects the earlier thesis, but with the knowledge of your traits expressed throughout the essay
This essay is a basic form of an argument essay. The essay should make an argument such as that the person or character selected is worthy of admiration because of the traits selected.
Criteria for Success
A successful essay:
Meets basic requirements of the assignment
Has been written by the student submitting the essay, for this class, and for this semester,

erland.
Characteristics of a Main News Story:
1. General Content: Start with the facts: who, what, when, where, how (feel free to fabricate unknown details for the purpose of this project)
2. Interviews: Provide no less than one “interview” in which characters involved are quoted in response to the event
3. Tone: Be objective in tone. A quality news story is devoid of opinion or conjecture. Represent both sides of the issue if multiple viewpoints exist. It may mean getting interviews from differing parties.
4. Headline: Don’t underestimate the importance of the headline. Reporters use sensationalized and emotionally charged language to catch the reader’s attention. This can be a challenge because you also keep a headline concise.
5. Structure: Inverted pyramid structure. Journalists usually describe the organization or structure of a news story as an inverted pyramid. The essential and most interesting elements of a story are put at the beginning, with supporting information following in order of diminishing importance.
6. Length: CPS: 500 words minimum; Hon: 600 words minimum
7. Format: MLA, submit a Google doc
