I. Introduction
A vector is an arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity. Vectors are useful in combining velocities that are not parallel. The sum of two or more component vectors is called a resultant.
When the vectors are not at right angles to each other, the resultant is found by constructing a parallelogram. The parallelogram is constructed with the two vectors as sides. The resultant of the parallelogram is its diagonal.
Equilibrant vector on the other hand, is a single vector that would balance the original vectors taken together.
An experiment was conducted to determine the difference between using graphical, analytical and experimental method in getting the resultant. A force table, weight holders, a set of slotted masses (200g and 249g), ruler, protractor, spring scale and triple beam balance were used. Each group has its own assigned mass and forces as well as a force table. Weight hangers were attached to two strings tied to the center ring of the force table, where two slotted masses, one 200g and the other 249g were hung according to their specified directions. The center ring was anchored to the nail positioned at the platform’s center while the upper ring of the spring scale was attached to the free end of the third ring. After attaching the spring balance, its hook was pulled and the reading on the scale and the direction of the pull at which the two forces (hanging mass) are “balanced.” “Balance” was determined.

The velocity computed by using tangent lines was found to be higher than the average velocity. The results were also found to have irregular values. It is noticed that after covering the distance of 40 cm, the velocity went down. The velocity between the distance of 40 cm and 70 cm were found to be equal.
On the other hand, the computed values of the acceleration were also irregular. Acceleration at the distance of 10 cm and 40 cm were found to be equal. Acceleration would not change even if the group used a larger marble. It would make almost no difference in the values acquired.
Errors may have been one of the causes of irregularities seen between velocity and acceleration. Maybe one of the problems that we encountered was the irregularity of the time. Because of this, the other computations were affected.

V = df – di tf - ti
V1 = 15 – 5 = 10 = 20

This shows that there is a difference of 2cm between A and B, and B
So using this formula but with the data we collected from our first attempt, this is what it would look like; Tan(60°) x 23m = 39m. As you can tell this answer collected from our first attempt is very well incorrect, but at the time, our group did not know this.

Numerous people may not realize what he or she discards may in fact be of use to someone in a homeless condition, therefore education for the public to instruct them to donate more items should be considered. If collaboration could be made between the local refuse plants and the homeless shelters to help educate the public, more usable items could be donated rather than discarded as trash. This could be as simple as a correspondence attached to the monthly bills for all the residents of a
There are many technicalities and terms associated with a successful device. Some of the main factors come from the materials used, and where they were used in the structure. Some are best used in one place, or another. All of this must be taken into consideration when deciding on how to best utilize the physics and forces applied to the boomerang. As it is a simple machine, it dominates in simplicity for a somewhat daunting task.
The second amendment affects us today by limiting our rights to posses a gun. Civilians cannot expect to use their household weapons for militia duty, although they can keep them if there is a criminal attack for for hunting ect. In 2008 the judiciary treated the second amendment almost as a dead letter. The Supreme Court invalidated a federal law that forbade nearly all civilians possessing handguns in the nation's capital. Majority rules that the language and history of the Second Amendment showed that it protects a private right for individuals to have arms for their own defense. Some disagree with this saying that the amendment protects their right as an individual. They argued that if it did protect an individual right to have arms for
In our nature, we have the habit of throwing as much stuff possible even if it’s something that is still usable. A small imperfection makes them liable to throw it away, yet there are people out there who have nothing to eat and are constantly hunting for food, even if it isn’t a real hot meal. They just need something to fulfill their digestive need. Food should be viewed with much more value and respect rather than ignoring and throwing it as if it’s trash and not life essential. The statement we constantly hear but fail to acknowledge is that “some people have it much worse” and there are those who really do. People who don’t have a cent to their name are going through dumpsters and eating the food that you threw out. There’s a huge amount of homeless people in our nation yet our government still fails to take action. It is for this reason that I believe the community should recognize homelessness as a problem and petition government to take action against it.
For many homeless people, it is some strange turn of events causes them to lose everything. Then after months of rejection, they begin drinking and doing drugs. Eventually, the emptiness sets in so they begin talking to themselves. They don’t have anywhere to shower or get the mail. Eventually, they lose touch with society.

The creation of a strong working psychological contract is dependant on the commitment and effectiveness of the employee within in the organisation. The extent to which their own expectations of what the organization will provide for them and what they owe the organisation in return must match the organisation’s expectations of what it will give and get in return (Schein, 1965).

Some view being ready for college as the curriculum a student takes on in secondary schools. Achieve (2004) views college and workplace readiness as taking rigorous course to prepare for college and passing English and Mathematics benchmarks. This definition is closely related to the one provide by the NAGB. The students’ readiness is based on assessments and grade point averages. The whole
Students are encouraged at a young age by parents and educators to plan well in advance for college and pressured to do great on a daily basis in school. Some high school students do not put forth enough effort to plan for college until their senior year. Some high school seniors think by making great grades they do not have to worry about getting into college, while others plan and prep as if it is the only thing that is important...
In this assessment of the projectile motion of an object, I found that it can be applied to many useful situations in our daily lives. There are many different equations and theorems to apply to an object in motion to either find the path of motion, the displacement, velocity, acceleration, and time of the object in the air.
