Optimization of a Volleyball Serve - Free Essay Example

Rationale Volleyball is one of my favorite sports that I play although I only play two and that was the reason I decided to focus my mathematical exploration on this simple topic. When told I had to do this exploration, I instantly started searching for topics and/or things I could do but nothing interested me. After looking at the stimuli given to me and many other examples, I decided that I would stick to what I was known for: sports†volleyball and basketball. I thought that relating this mathematical exploration to a more personal matter would be the better choice. Having played volleyball from my 8th grade year to my senior year in high school, I know that serving is an important part of the game, but my question was How would I model this? Serving a volleyball is one of the most important factors in the game of volleyball and I knew that I would need to consider the physics of serving. Projectile motion is something that most definitely needs to be considered when talking about the optimization of a serve. Introduction Volleyball is an internationally renowned sport that is currently ranked as number 5 according to world atlas. It is essentially a game that consists of two teams, normally six players, in which a ball is hit over a high net. The aim of the game is to score points by forcing the ball on the opponents side of the court. One prevalent strategy is the use of a serve. Ive played it since my 8th grade year of middle school and Ive been a great server ever since. An optimized serve will either result in a point (due to it not being returned) or weakly returned allowing the serving team to use this to an advantage. In this paper, I will construct a model to interpret the optimization of a volleyball serve. Figure 1: The steps of serving a volleyball In order to correct model serving optimization, I will base the optimization of the serve on the dimensions of the court and the volleyball and the forces acting upon the ball. I realized that I first needed to consider these small factors when it comes to serving. The other most important forces to be considered are: the initial velocity put on the ball by the player, the force of the spin of the ball, and the distance the ball has traveled. Not only those things but also gravity plays a crucial role in the serving of a volleyball as it gravitates towards the Earth. Dimensions and Limits A volleyball has a diameter, d, of slightly over 8.15 inches and weighs about 10 ounces when rounded from 9.9 oz. The ball has shallow grooves along its outer shell which affect the way the air moves around the ball. When hit hard without spin, the ball tends to flutter in the air, moving erratically as it descends toward the ground. When hit hard with a spin, the ball tends to gravitate towards the ground faster with what is known as topspin. Figure 2: A diagram of a volleyball court with dimensions. Servers must serve behind the end lines. A typical volleyball court is 29 feet, 6 in. (9 m) wide by 59 feet long (18 m) in the shape of a rectangle (see Figure 2). The net in NCAA womens volleyball is 7 feet, 4 in. high. The net in the middle separates the court into two equal playing areas. Spreading from the end of each side of the court is an area from which the ball is served. The server may stand at any spot behind the line to serve efficiently. To calculate these models, x will represent the distance the ball travels horizontally, while h will be the height of the ball. The total distance will be represented by dt. In order for the ball to be served, one must hit the ball with an initial speed, therefore, VI will represent the initial velocity of the ball. As air resistance plays a big part in this model, time will be a factor to the model. Time will be represented as t due to the faster a ball comes, the less time an opponent has to get to the ball and return it. Explanations of Models C.1- Spin We must take into account the spinning of the ball. A spin on the ball allows the ball to move faster towards the ground on the opponents side of the court. It creates a force that along with the initial velocity that would make a serve a good serve that may end with an awarding point. A top spinning ball is where the top of the ball in spinning in the same direction of its projected motion; thus causing the molecules on the ball to gravitate towards the means of the Earth due to gravity. Because of this very reason, servers tend to typically use this strategy rather than a serve with no spin to acquire a quick point. To calculate this model, we must take the magnitude of the force and relate it to the angular velocity of the ball, which will be represented by ?†°. Angular velocity is a velocity that applies to objects that move along a circular path. Since, due to the spin, the magnitude is proportional to the angular velocity and the velocity of the actual volleyball. Figure 3: Diagram Dimensions of a Spinning Volleyball C.2- Gravity This model is based off assumptions that gravity is the only force acting upon the ball. In this model, the magnitude of the gravity force will be mg in the y direction since the ball is traveling downwards; m is the mass of the ball and g equals 9.8 meters/second2 whereas its the acceleration due to gravity. Also, the ball will move with a constant velocity in the x direction until it completes its path by landing on the ground. This model will be represented by the force equations of (see figure 3): Fx = 0 Fy = -mg? ¬? ¬ The time the ball is in the air can be calculated by the square root of the distance multiplied by 2, 2dv, divided by the acceleration of gravity: T = ?â‚ ¬?(2dt/g)

What to Look For When Writing a Search Research Paper

What to Look For When Writing a Search Research PaperStudents and scholars who are considering pursuing a career in the business of search research will find that writing a search research paper is of considerable importance. As a professional involved in this area of study, you need to be able to grasp the reasoning behind searches and the reasons why they have evolved. You will also need to understand why this development has taken place and if you wish to take part in this activity, what the business of search research is really about.In the past, the primary reason for searching for information was the desire to obtain it from an unlimited number of sources. The demand for this information could often leave a lot of different organizations with large numbers of documents, many of which were in poor condition and only documents that a searcher wanted to obtain. This led to the establishment of the first search firms, with the hope of providing comprehensive information about a wid e range of companies. This did not work out well, as this function became too specialized.Currently, the main reason for carrying out searches is for business: to find out how other businesses are performing in comparison to your own. It is not uncommon for an entrepreneur to undertake a search on a competitor's activities, whether there is any basis for doing so or not. This is the nature of business, and the principal motivation behind searches. Having taken this point into consideration, several changes have been introduced in search firms that have served to limit their scope.In the past, search research firms would undertake searches over a huge number of keywords. These would then be stored in a spreadsheet, with the searches carried out by an individual using a program. However, it was discovered that for increased efficiency and accuracy, it was necessary to carry out the searches on individuals instead of businesses. Search firms employed advanced technology to conduct this task, and now take data from an individual and analyze it.However, it is also important to be aware of various criteria for choosing the right company to carry out a search for you. While it is essential to choose a firm that employs the most advanced technology available, this does not mean that you should be satisfied with a traditional research company. Instead, use as much information as possible to help you choose the right firm.At the same time, ensure that the firm you choose has strong records of successfully conducting its search operations. A good record is an essential requirement for any business that wishes to increase its prospects. A solid record makes it easier for the firm to continue operating and to perform at its best, as it maintains a history of performing effective searches and providing excellent results. Make sure that the firm you choose has a good record of delivering excellent results.When you carry out a search for your organization, you will be trying to identify the current market trends, the attributes of the product or service, and how it performs in the market. It is imperative that you read up on these points, as well as the assumptions and theories that have made them popular. If you think about how you want to present your findings, consider what will impress readers. The more positive things you can write about your product or service, the better.To sum up, when you are involved in search research, there are many factors that you need to keep in mind. Always keep in mind that you are writing a search research paper for publication, and the purpose is to answer all the questions that the reader may have.
