For example, A could be going faster right now but at constant speed (aA = 0), while B is going slower now but has his gas pedal on (aB> 0), so B will overtake A soon. However, we really have no idea what the situation is, so without knowledge of the acceleration along with the velocity, we can’t predict anything. 12. They are certainly not always the same. Check Worksheet #2 for a good example: the girl going around the carousel has zero displacement and thus zero average velocity, but certainly went at a nonzero average speed as she went around the circle. 13. To her, the ball looks like it drops straight down, despite the train’s speed (vBT is the same as a normal falling ball). But to someone standing still on the earth outside, they see the ball moving in a curved parabolic path, as if it’s launched with an initial velocity of vBE = (175 mph, 0), because it’s “boosted” by the train. WP Answer Equation and quick explanation 14. 4.87 m/s2 v = v0 + at 15. 4.77 m/s v2 = v02 + 2aΔx 16. 4.35 m/s avg speed = total distance / total time 17. 4.4 m Use the projectile kinematics equations, with Δx = 48m to solve for t (it’s 2.44 seconds), then use t in the y equation to find Δy 18. a) v = v0 – gt Eq. 1 b) Δy = v0t – ½ gt2 Eq. 2 c) Δy = v02 / (2g) Eq...

...PREFACE: To The Evaluators Of My Training Program If we look at our surroundings, all the human beings would be wearing some cloth, most of which is woven. Today the average consumption of textile products per person per year is 6.7 Kg. The world population has crossed the six billion figure, so more than 40 million tons of fabric is utilized by the mankind of world each year. Indeed both consumption per person and population are increasing at a faster pace. Consumption per person is confidently expected to increase after December 2004, as WTO would eliminate the quota costs, import duties and other such tariffs. To be competitive in the textile market, the manufacturers of this industry will have to transfer this benefit of low cost to the customers, which in turn would encourage the customers to buy more. This process would yield economies of scale for the producers and thus the textile companies will achieve enormous growth. Pakistan has competitive edge over many other countries in the textile industry, so it will more focus and capitalize on this concern. This gives a view of future prospects of opportunities in textile and importance of textile products. More specifically the shade, look, handfeel of fabric and durability of shade are the crucial factors of concern for the textile customers (these factors are expected to gain more attention of customers in future). These factors are complied in dyeing processes. Kohinoor Dyeing Mills Ltd. (KDML) is involved in the...

...Legal Memo To: Attorney John Smith, Esquire From: Paralegal Re: Westen Vs. Jane Date: March 18, 2002 This memorandum follows your recent assignment where in you requested that I contact Mr. Mark Vision, who witnessed our client Mary Jane’s accident, and determine where Mr. Vision was in association with the accident, the approximate speed of the other vehicle, the weather conditions and any other information that would be useful in either shifting liability or alleging contributory negligence on the part of plaintiff/driver. Analysis of the Interview I contacted Mr. Mark Vision on March 4, 2002. He is an African American male, very tall with a slim build. He wore business casual clothes and he seemed a little nervous, but he was very respectful and well mannered. He was very forthcoming with all of the questions he was asked in the interview. He seemed very truthful and reliable and answered every question with a matter-of- fact attitude. He remembered the entire accident very vividly. He would make a favorable witness for our case, because he feels that Ms. Jane is not guilty. Mr. Vision advised me that he was on the way to work at his part-time job Saturday March 18, 2002. The reason he did not give a statement at the time of the accident, was because he is the Manager and had to be at the company early to let the other workers in and didn’t want to keep them waiting. But Mr. Vision did give the Police his contact information. It was raining that...

...meters), or equivalently to move +8 meters from where he started. At 4 seconds, he will have a velocity of 4 m/s On the Position-Time graph, the line is a positive consistent rise. This is because his position is going in a positive direction as well as the time is going in a consistent positive direction. Explanation for graph’s appearance –after actually performing the activity. Velocity-Time Graph On the Velocity-Time graph, the line is straight across at 2 m/s because the velocity does not change because of the consistent speed of the man walking to the house. Since the velocity is constant the acceleration is zero. Explanation for graph’s appearance - after actually performing the activity. Acceleration –Time Graph On the Acceleration-Time graph, the line is flat and straight across at the 0 m/s line because the man does not accelerate. He just walks at a consistent pace to the house.

...the gas mileage. There are no gas station in the dessert so it has to have a fuel efficient way of traveling. The next obstacle established in the challenge is the terrain the higher-quality graded dirt with winding rocky-mountain passes and a tunnel. So, there’s loose dirt mountains and a tunnel all things that can cause the vehicle to lose grip of it terrain, lose control of the direction it wishes to go and also one’s sense of direction as though the location is a dessert and everything better much looks the same for miles. The last major obstacle pointed out in the challenge is the various speed limits which in turn could hinder the time of arrival if too many mistakes are made during the race. With using a combination of speeds ranging from 5-50mph the driver would have to travel at the least 17.5 miles in one hour using those speed limits. The fallacy of considering the average speed posted in the challenge is that there could be lots of wind the day of the race that is one does not carefully drive could easily be blown of track driving on that loose dirt. Ways of preparing the vehicle for this race would be to if possible find shortcuts or detours that guide us around the dangerous obstacles and also help us to slim down our finishing time. Failures that are possible to completely take the vehicle out of the race would be that it could run over a sharp object in the terrain that blows one or more of the tires and we don’t have a replacement to cover the blowout, also seeing...

...When Hennessey made the Venom GT, they had a singular goal in mind. They were going to create the fastest car ever made. On Valentine’s day 2014, they brought their car out to secret runway in a classified facility, where the like minded individuals brought their car up to a staggering 270.49 miles per hour before testing out their Brembo carbon ceramic brakes. Unofficially, the Hennessey Venom GT broke the production car speed record that day, however Guinness requires more loops to leap beyond being the fastest. To hold the title of fastest production car Guinness demands that more guidelines be followed. The car in question must have; at minimum; 30 models manufactured. The record keeper also requires the automaker to run the same straight forwards and backwards before using the average as the official record. Unfortunately, Hennessey will only ever assemble 29 Venom GTs, and the National Aeronautics and Space Administration (NASA) did...

...The essay “I Killed Britney Spears” was written by the London based journalist Jean Hanna Edelstein, in 2008. Edelstein was born in New York, 1981 to an American father, and Scottish mother. She later moved (1999) to London, where she studied economics and political science. She has also lived in Montreal, Berlin. She has an online-based blog, where she uploads a few essays and inputs – inputs that are all backed up by her academic background. Despite the online essays, her first official published book was in 2009. “I Killed Britney Spears” is a (non-fiction) personal essay, with a first person narrator which makes the essay identifiable. Edelstein clearly wrote this essay to highlight a few consequences and flaws in the relationship between fan and idol. Most of these flaws are shown in the age 13-18. These years are filled with the confusion that follows the transition from child to adult. Edelstein might have thought about this particular transition and thereby, intending the text to be read by these confused adolescents. The text “I Killed Britney Spears” was written in 2008, a year of great turmoil for the star Britney Spears. She was fighting over the custody of her children, she had been in rehab and just cut off her hair. All these events generated a lot of public attention. Mostly negative attention. Many of the “Spears” fans (including Edelstein herself) who identified themselves with her, were emotionally hit by Britney’s instability. The intention of Edelstein...

...Antidepressants: It can either heal or harm you If you are considering antidepressants, think again. Antidepressants are designed to relieve one’s self from depression on the contrary, it still harmfully affect humans. Studies show that antidepressant users are more likely in peril than those of non-users. Researchers found that it affects all the systems in the body. Antidepressants are not efficient medicine though it may lessen depression to increase the level of happiness. Common antidepressant users blame their anxiety as the root of their medicine dependency. Depression is a dreadful nightmare anyone would ever want to escape. And this is why people use different medicine to overcome this horror. Often, personal problems cause their depression. While not all reasons may be their misery’s fault, certain and various causes may also take place. Famous popstar Britney Spears claimed that she was being prescribed antidepressants at the age of 18. She would take the medicine everytime she feels restless and tired, but then the continuous intake made her mental state even worse. There are times she would wake up feeling depressed. As this horror frightened her, she decided not to take it again. Certain cases lead to different diseases. Even worse, it can lead to death. There are a lot of things you can do to replace this approach. One way is by simply listening to music. Using antidepressants can surely eliminate your burden, but will it last longer than you think?

...Tobi Gonzalez 2/25/13 Motion is Relative 1. The two units of measurement are distance and time. 2. The kind of speed is registered by an automobile speedometer is instantaneous speed. 3. Average speed is the speed averaged over duration of time. Usually the total distance covered divided by the total time. Instantaneous speed is the speed given at that instant within that span of time, measured with a real time speedometer. 4. The average speed in kilometers per hour for a horse that gallops a distance of 15 km in a time of 30 min is: Average speed = 15 km/30 min = 15 km/0.5 h = 30 km/h 5. Speed is the distance covered per unit of time. Acceleration is the rate in which an object changes its velocity. 6. If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, it does maintain a constant speed but not a constant velocity. The velocity never changed, only the direction it’s traveling. 7. Velocity is change in displacement, change in position over a period of time, while Acceleration is change in velocity over a time period. 8. The acceleration of a car that increases its velocity from 0, to 100 km/h in 10s is 10km/h*s 9. The acceleration of a car that maintains a constant velocity of 100 km/h for 10s is 0 km/h*s. Some of my classmates get this question wrong but the last question right because they fail to read the question. In the last question there was a change in velocity.
