Equations and Problem-Solving

* An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance travelled before take-off.

-------------------------------------------------
Solutions
Given: a = +3.2 m/s2| t = 32.8 s| vi = 0 m/s|
| Find:d = ??|

d = VI*t + 0.5*a*t2
d = (0 m/s)*(32.8 s) + 0.5*(3.20 m/s2)*(32.8 s)2
d = 1720 m

Equations and Problem-Solving

* A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.

Given: d = 110 m| t = 5.21 s| vi = 0 m/s|
| Find:a =??|

d = VI*t + 0.5*a*t2
110 m = (0 m/s)*(5.21 s) + 0.5*(a)*(5.21 s)2
110 m = (13.57 s2)*a
a = (110 m)/ (13.57 s2)
a = 8.10 m/ s2

Equations and Problem-Solving

* Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?

-------------------------------------------------
Solutions
Given: vi = 0 m/s| vf = 44 m/s| t = 1.80 s|
| Find:a =??d =??|

a = (Delta v)/t
a = (444 m/s - 0 m/s)/ (1.80 s)
a = 247 m/s2
d = VI*t + 0.5*a*t2
d = (0 m/s)*(1.80 s) + 0.5*(247 m/s2)*(1.80 s)2
d = 0 m + 400 m
d = 400 m
(Note: the d can also be calculated using the equation vf2 = vi2 + 2*a*d) -------------------------------------------------

Younger Sibling Problems
Younger siblings can be a problem that will lead to a bigger problem, your parents being angry at you for never being home. My younger brothers, CJ and Colin, are obnoxious and very annoying. CJ is six years younger than me and Colin is eight years younger than me. You wouldn’t think that they would be a problem to me since there is such an age difference between us, but they are. Since my brothers annoy me I am rarely home; my parents get angry with me for it, but there is not much I can do when both of my brothers get on my nerves; most of the time they do it at the same time. A big problem for me is that my brothers annoy me so much that I have to leave and go somewhere that does not involve my brothers, which causes my parents to be mad at me.
CJ, the older brother, is so mouthy. He always has something to say to me when I try talk to him; most of the time it is not nice, it is usually something rude. It seems like he was raised not to be respectful, but he wasn’t raised that way. For example, one day I asked him nicely to grab my cellphone and his reply was “why don’t you get up and get it yourself, both of your legs work, right?” I do not know why he acts the way he does, but it gets on my nerves. CJ and I always argue about everything. For instance, when I am in the living room watching TV he will try to play the Xbox, but I...

...Decision-Making & ProblemSolving
“Thinking is any mental activity that helps formulate or solve a problem, make a decision, or fulfill a desire to understand. It is a searching for answers, a reaching for meaning.” –Vincent Ryan Ruggiero
* Develop evidence to support views
* Analyze situations carefully
* Discuss subjects in an organized way
* Predict the consequences of actions
* Weigh alternatives
* Generate and organize ideas
* Form and apply concepts
* Design systematic plans of action
A 5 Step ProblemSolving Strategy
1. Specify the problem – the first step to solving a problem is to identify it as specifically as possible. It involves evaluating the present state and determining how it differs from the goal state.
2. Analyze the problem - analyzing the problem involves learning as much as you can about it. It may be necessary to look beyond the obvious, surface situation, to stretch your imagination and reach for more creative options.
* seek other perspectives (ask other people there opinion)
* be flexible in your analysis
* consider various strands of impact
* brainstorm about all possibilities and implications (use some brainstorm activities)
* Research problems for which you lack complete information. Get help.

ProblemSolving
We are faced with different types of problems in our everyday life. Every problem requires a solution to resolve it. There maybe more than one solution to a problem.
Problem-solving involves identifying, analyzing and resolving problems using logic, reasoning skills and analytical skills.
A problem is a discrepancy between what is required and what exists. Problem can be simple or complex depending on its nature. A single-task problem is usually a relatively simple problem, whereas a multi-task problem is usually more complex and may require more resources to solve.
A solution is a procedure consisting of a set of instructions that, if followed in order, achieve the required result.

...about generational differences in workplaces. Firstly, causes, which are the lack of understanding probably due to biases, common attitudes and tools of communication worth an in-depth investigation, followed by consequences of the problem, that is confusion, mistanding, and even confilcits of each other. Ultimately, solutions of the problem due to generational differences in a workplace will be delineated.
Communication is the conveying of ideas together with absorbing one’s opinions (Sinclair, 2001). ‘We have two ears and one mouth so that we can listen twice as much as we speak’ – to communicate effectively, we should put effort into listening to and thus understanding each other (Epictetus). However, an effective communication is exactly what is lacking between different generations, which is one of the major problems in a workplace.
First of all, generations do not understand one another well probably due to each’s biases against the others: the idea that the older generations are stubborn and reluctant to accept new opinions is deep-rooted among Gen Y-ers, the younger generations, while Gen X-ers, the older generations deem that the youngsters nowadays are lackadaisical. What must not be overlooked is that the mass media has worsened the problem by developing terms like “70s’”, “80s’” and “90s’” that encompass stereotypical and generalizing qualities regarding each group, causing even greater prejudice...

...Where there is a problem there is a solution. No matter how complicated nor how elusive the solution is one is always there. Problems are the basis of jobs and careers: restaurants for hunger, movies and video games for boredom, news for information etc. However, with basic problems that have a set solution there are a variety of ways to solve it.
Working backwards, although slightly different, is a widely used and very effective way ofsolvingproblems. 1 (Referring to page "Problem I") Most people would look at this problem and would loathe solving it because it would involve creating a long complicated algebraic problem. Using the method of working backwards even a child who hasn't learned algebra can solve the same problem and maybe even faster. Working backwards takes one to the answer and then works backwards throughout the problem to see how the solution was reached.
Means-Ends analysis is another way to solve a problem. "...combines aspects of both forward and backward reasoning in that both the condition and action portions of rules are looked at when considering which rule to apply." In some ways is the same as Working backwards, but different in the aspect of seeing the answer and finding the means it took to make it to that answer. 2 "However, even without the ordering of...

...information in tubular form. To know
what such data means you will have to read the tables and apply what you have
learned. Your notes should focus on the details you will need to identify the
business problems involved in the case, the issues critical to solving those
problems, as well as resources available to the managers in the case. Those
notes will be helpful in producing a case solution.
Look for (business) problem(s): Do not just rephrase the obvious problems
stated in the case, but try to identify the real problems faced by the organization.
In each case, at least one fundamental problem is present.
Specify an objective for the managers involved: Once you have identified
one or more business problems present in the case, think about the outcome(s)
you would most hope to see for the company and people you have read about. If
you were asked to consult on this company’s problems – and that is the role
most public relations students are playing as they read a case study – what
results would you hope for? Don’t limit your thinking to what the company should
do, but what the most successful outcome would look like. Be specific about how
the company will know if it succeeded. Quantify the desired results whenever
you can.
Identify alternatives: After identifying the problem, start thinking about the
