Problems (Chapter 3) Review Example problems #1 - 12 by yourself. Problem 3 (page 96): A web page designer creates an animation in which a dot on a computer screen has a position of r = [4 cm + (2.5 cm/s2)t2]i + (5 cm/s)t j. a) Find the magnitude and direction of the dot’s average velocity between t = 0 and t = 2 s. b) Find the magnitude and direction of the instantaneous velocity at t = 0‚ t = 1 s‚ nd t = 2 s. c) Sketch the dot’s trajectory from t = 0 to t = 2 s‚ and show the velocities

The Domino Effect 9-26-01 Abstract: In this experiment dominos were used to investigate how distance‚ time‚ and average speed is interrelated by maximizing the speed of falling dominoes. This was done by lining up 28 dominos up against a meter stick 0.5 cm‚ 1.0 cm‚ 1.5 cm‚ 2.0 cm‚ and 2.5 cm away from each other. Before the experiment the average width of a domino was taken. At the beginning of each of these 5 trials the dominos were lined up against the meter stick. The lengths of all the dominoes

Overview of Various Types of Sights Why choose a holographic sight‚ otherwise known as the red dot sight‚ when there are other options such as telescopic sights and laser sights? What advantages does the holographic sight have over these other sight systems and why is it the weapon of choice for the military? It is true that the holographic sight is the most used aiming system in modern warfare but how far does its advantages take the shooter to when compared to what consumers already

Introduction The basic premise behind the learning curve concept is the improvement in performance of process due to repetitive nature of tasks operated by individual or organization again and again. This theory is based on three fundamental assumptions which is as follows: 1. The time required for completion of task decreases as it is repeated number of times 2. The percentage of improvement decreases with corresponding increase in volume of units‚ 3. The rate of improvement is predictable over

Shawni Guest CRN: 10986 1/3/09 Rene Descartes Often credited with being called “The Father of Modern Philosophy”‚ this title is supported by his contributions to philosophy and mathematics. The coordinate system‚ used today‚ is accredited to him along with many other mathematical contributions. He also had many contributions to philosophy‚ including his most famous‚ Meditations on First Philosophy. Every time you graph an equation on a Cartesian coordinate system‚ you are using the work

Chapter 2 1. A consumer prefers more to less of every good. Her income rises‚ and the price of one of the goods falls while other prices stay constant. These changes must have made her better of. TRUE 2. A decrease in income pivots the budget line around the bundle initially consumed. FALSE 3. If all prices are doubled and money income is left the same‚ the budget set does not change because relative prices don ’t change. FALSE 4. If all prices double and income triples‚ then the

Creating a Competitive Salary Structure INTRODUCTION Each employee in an organization is paid a salary. Salaries vary greatly‚ with executives earning as much as (or greater than) 100 times an entry-level employee’s salary. This variation is not by chance. It is rationally established through a salary structure – a hierarchy of salaries. Organizations develop this structure based upon internal factors (such as current rates‚ job relationships‚ and custom) and external factors (such as labor

Introduction A traverse consists a series of straight line of known length related one another by known angles between the line. The points defining the ends of the traverse lines are called traverse stations. Traverse survey is a method of establishing control points‚ their position being determined by measuring the distances between the traverse station which serve as control points and the angles subtended at the various stations by their adjacent stations. The angles
