Download file to see previous pages Since the gravitational pull acts downwards (vertical sense) then the horizontal and vertical components can be treated separately. Thus, the maximum height traveled by the body upwards can be calculated (Warren 73). For instance, a cannon shoots a ten kilograms cannon balls straight upwards, with a muzzle velocity of say 860 m/s, and then ignoring air resistance the maximum height attained by the cannon balls can be found. Taking the initial velocity in the vertical direction of the cannon ball to be vi and bearing in mind that the acceleration due to gravity is acting in the opposite direction (downwards).
At the point when the cannonball attains the maximum height, it has zero velocity thus vf = 0. At this point, the ball starts to accelerate downwards. The equation below is used to calculate the cannon’s highest point that it reaches before it starts falling downwards (Warren 72).
Thus, the ball will go up to thirty-eight kilometers or approximately twenty-four miles (Serway, Jewett and Peroomian 20). Theoretically, the ball should come back and attain the velocity same as the launching velocity as it falls at the same point of launching, that is 860 m/s.
At each angle of elevation, the initial velocities were noted (McGinnis 73). The same procedure was repeated for the ball with a mass of 5.50 grams. The results were tabulated in a table as shown below:
The result of the heights corresponding to every velocity was obtained, and curves were drawn for every mass. The results were as shown below. The table shows the results obtained for the ball of mass 9.5 g.
The data obtained for the two balls was tabulated, and the maximum height reached by the ball at each launch relative to the angle of elevation was found (Breithaupt 26). The maximum height was determined using the formulae in the equation (7). H max = …………………………………. (7).
Each ball was launched at its time, and the muzzle velocities were maintained ...Download file to see next pagesRead More

However, it works in an industry where the basis of competition change with the introduction of every new product and existing players will have to improve the capabilities in order to sustain in the market. The introduction of Apple Iphone and other Android based phones has posed a great threat to RIM because other products are gradually taking the market. (Peers ). One of the most effective ways to counter such challenge is to improve the research...

As a violin string vibrates, its motional energy is changing rapidly with time.(T) The change is observable as it occurs d. High pitched violin strings are the most likely to break.(T) High pitched strings have least mass per unit length; very thin, therefore they are likely to break or snap. e.

Electro-Motion Devices
...Electro-motion Devices Electro-Motion devices are evolving in a number of applications. In many environments, devices operated by electric power have been developed. This is the case with the petrochemical and process industries as well. The process industries work by suitably controlling the temperatures, pressures and flow of the chemicals through their pipes and ducts. This flow is continuously and closely controlled by valves. Ball valve based control is very critical in most of the process industry application. Therefore, this novel electro-motion device has been developed to operate as a ball valve. The Electro-Motion Ball Valve makes use an electric field that would rotate the ball valve by 90 degrees keeping the valve open... . This...

Projectile
...September 8, Projectile Lab Introduction Projectile motion refers to a form of motion in which a body referred to as a projectile is catapulted obliquely near the surface of the earth. Using equations of motion, this motion can then be analyzed to find the distance, time and the speed the object moves with. This experiment’s main objective is to determine the velocity with which a projectile is launched with. Methodology Part A The projectile was positioned in such a way that it launches the ball horizontally. The height where the ball leaves was then recorded. The...

Projectile Motion
... Projectile Motion This refers to the motion under the effect of gravity. This experiment is going to investigate four aspects of projectile motion. Objectives of the experiment 1. To show that horizontal and vertical components of motion can be treated separately 2. To show that the horizontal motion takes place at constant velocity 3. To show that the range is the same for complimentary angles 4. To show that the trajectory is a parabola Discussion of the four aspects of the experiment The first part was the experiment following the procedure in part 3.1 was meant to verify that the ball launched at different speeds hit the ground at the same time interval after being shot while the range will depend on the initial velocity... that is...

Leap motion
...Leap Motion Leap Motion is one type of technology that has the potential of changing the way humansinteract with the computer. Comparable to sci-fi movie, the device allows one to interact with other devices through simple hand movements. It is a product of Holtz who had developed powerful algorithms while undergoing a PhD program. His success in coming up with the technology was a result of him believing that he had the capability of transforming the human machine interface through combining the learnt algorithms with simple hardware. His close correlation with Buckwald contributed significantly towards attraction of investors who supported their technological project. Before developing Leap...

Rotational Motion
The mass and dimensions of the steel block were measured together with the errors due to measurement. The Data studio (DS) data acquisition program was opened and a file Desktop-pirtlabs-PHY 122-Rotational motion. The file was preset to record θ (t) and ω (t). Part I: The block was attached through its shortest axis onto the rotary encoder. The string was put on the medium pulley and wind it up entirely in a direction so it will unwind CCW (counterclockwise) when facing the pulley. The readings were taken. Therefore, the dynamic moment of inertia along the short axis is greater than one for the long axis. However, the theoretically calculated static moment of inertia lies within the range defined by the dynamic moments...

...than one with high packet loss. The available function restricts a server from serving more clients if it is already servicing a load near its maximum load. The likely function is used to determine which of the available servers has the content being requested by a client. The Akamai CDN uses Query, a custom-developed distributed monitoring system, to manage all of its servers (Cohen, Repantis, McDermott, Smith & Wein, 2010). The CDN supports client businesses that run all day, every day. Network or server outages of even a tiny period of time can cause huge losses. Query was hence developed to provide real-time monitoring for all these distributed servers. Query detects problems and measures performance of each edge...

Wuthering Height
...Wuthering Heights Introduction ‘Wuthering Heights, a novel by Emily Bronte is an incredibly intricate narrative. In it, we find generations of characters, stories that are full of stories and flashbacks that minute the plot about who married whom. The theme of love is dominantly explored in the novel (Bhattacharyya 93). Of such kind is the love between Heathcliff and Catherine that turns out to be self-destructive. A love triangle manifests in the theme of love. Therefore, this essay explores the theme of love and the character Heathcliff within the context of Bronte’s ‘Withering Heights’. Theme of Love in Wuthering Heights The theme of love in the novel is predominantly...
