Description
the coefficient of kinetic friction between a couch and the floor is 0.81. If the couch has a mass of 71kg and you push it with force of 650N, what is the net force on the couch as it slides?

Explanation & Answer
Thank you for the opportunity to help you with your question!
the friction force= KE*mass of object*gravity
Fforce=0.81*71*9.8
friction=563.598N
on the horizontal direction, total force=650-friction
=(650-563.598)N
=86.402 N is the net force

Grantham University Week 7 Atom Models Discussion
Atom ModelsEach week, you will be asked to respond to the prompt or prompts in the discussion forum. Your initial post should be 75-150 words in length, and is due on Sunday. By Tuesday, you should respond to two additional posts from your peers. Our understanding of the atom has increased as new discoveries were made. Models are a useful way to represent theories and provide a means for testing them through experimentation. Models are a very useful tool, but they also have limitations. The model of the atom, from a tiny indestructible sphere to the quantum model of the atom, has evolved over time due to scientific discoveries. Choose at least three models of the atom and describe them. How do the models explain physical phenomena? What does the model explain that earlier models did not? What are the limitations of the model? What do they fail to explain?In your follow-up posts you should expand on the model analysis of a peer, add additional information about the models, or explain the connection between model described by a classmate and a model that you analyzed.

UCSD Physics for Life Sciences Skeleton Vector Lab Report
Part 1: The human body
At the end of this lab, you will find a picture of skeletons posing. For this picture, find the
Humerus, Radius, Femur, Tibia (both left and right sides). Treat each bone as a vector beginning at
one joint and ending at the other (you can choose, but be careful about negative signs). Then find
the x and y components of each bone vector in units of centimeters using a ruler. Once you have
the components, express each vector in (i,j) notation. Lastly, once you have each bone in vector
notation, find the magnitude and direction of each bone vector. You will have a total of eight
vectors that you will submit, along with your notes and calculations.
Part 2: The Animal Body
Now you will go online and find the skeleton of your favorite animal. Could be a horse, dog, cat,
dinosaur, etc. Then print out a picture of its skeleton and repeat the process from Part 1 for that
animal skeleton finding the position vectors for any four bones. If you simply do not have a
favorite, I included the picture of a dinosaur skeleton which you may use.

(Elastic and Inelastic Collisions) Experiment
3.1 Draw a diagram of all forces acting on each cart when they collide. Which forces will
influence the total P and KE most?
3.2 In our experiment, can we achieve a completely elastic collision? a completely inelastic
collision?
3.3 In an inelastic collision in a closed system, can some of the total momentum be lost?
Some of the kinetic energy?
3.4 In an elastic collision in a closed system, can some of the total momentum be lost? Some
of the kinetic energy be lost?
3.5 If kinetic energy is lost, where does it go? Does conservation of energy apply?

SNHU Online Classes Determining Requirements Paper
OverviewColleges and universities have begun offering online classes in order to attract a global audience. The concept of online classes was once considered challenging and complex. Today, schools have become more proficient in developing systems that serve thousands of students living anywhere in the world. These systems, sometimes called learning management systems (LMS), display course content, manage different user accounts, store grades, and more! In this assignment, you will research an LMS of your choice and how it provides its users with secured interaction, content, technical support, and more. You may also use your own experience as a student using Brightspace, Southern New Hampshire University’s LMS. With your knowledge of the system and your experience as a student, you will assume the role of a systems analyst who is designing a similar system for YOUser University, a new college offering online courses.PromptAssume the role of a systems analyst designing an LMS for YOUser University. You have been asked to determine different functional and nonfunctional requirements for the new LMS. You have also been asked to determine limitations and assumptions for your system design. You will be asked to provide a rationale for your work, and to support your reasoning with quality sources.Research learning management systems used at other colleges. Commonly used LMSs include Brightspace, Canvas, Blackboard, and Moodle. Additionally, you may consider your own experiences as a student. Here are a few questions you might consider to guide your research:What different functionalities do these systems have? What different functions do the systems perform?What behavioral properties do these systems have?Who are the different users and what types of access do they have?What platforms do these systems operate on?What security measures do these systems use?How do these systems back up and recover data?Based on your research, complete the Module Two Assignment Template included below. You will describe the requirements, assumptions, and limitations for the LMS you are designing for YOUser University. Be sure to do each of the following:Identify six different functional requirements for your LMS. For each requirement, you must include a rationale that explains why you chose that specific requirement.Identify six different nonfunctional requirements for your LMS. For each requirement, you must include a rationale that explains why you chose that specific requirement.Identify two assumptions and two limitations for this LMS design project. For each assumption and limitation, you must include a rationale that explains your choice.Finally, be sure to include citations in APA format for the sources you used to help you determine different requirements, or explain your rationale.TIP: The Module Two resources contain helpful links and examples of functional and nonfunctional requirements, assumptions, and limitations for different types of systems. These examples, in addition to your research, may be helpful to review as you complete this assignment.
