Accident transport and the congestion of traffic are becoming serious day by day Traffic accidents in Vietnam have been increasing at the alarming growth rate in the recent years. In 2008‚ there are more than 10.000 dead. The number dead from traffic accidents is much more than the number dead of cancer. The main reason is poor awareness of traffic participants such as driving after drinking wine‚ not wearing helmets

COEFFICIENT OF RESTITUTION The coefficient of restitution (e or COR) is defined as a number that serves as an index of elasticity for colliding bodies (Hall‚ 2012). Essentially‚ it measures the rebound of a ball after a collision with another object‚ like a golf club striking a stationary golf ball. A perfectly elastic ball will have a COR of 1‚ and a perfectly plastic ball will have a COR of 0. In golf‚ the coefficient of restitution comes into play when the club head impacts the ball‚ and

Introduction The aviation community generally defines CFIT as " any collision with land or water in which there was no detectable mechanical or equipment failure‚ where the pilot was in control of the aircraft but lost situational awareness and flew into terrain." (Bensyl‚ Moran‚ Conway‚ 2001‚ pg 1037) According to the National Transportation Safety Board (NTSB)‚ the Federal Aviation Administration (FAA) and the Flight Safety Foundation (FSF)‚ CFIT can be caused by many factors. Nevertheless‚ it

Collision Theory The theory proposes that molecules must collide in a particular way with a certain amount of energy to ultimately form a new product. This is because only a select portion of molecules during a reaction have enough energy and the correct orientation to break any existing bonds to form new ones at the moment of impact with other reactants. The very minimum amount of energy needed for this process to occur is referred to as activation energy. Collision theory explains why reaction

coefficient of restitution of a collision is the ratio of the square root of the rebound height (h) by the drop height (H). The coefficient of restitution varies from object to object and also according to the material which the object is impacted on (in this case bounced on). The value for the coefficient of restitution always ranges from 0 to 1 because ‘h’ cannot be greater than ‘H’. If a collision is perfectly elastic‚ the coefficient of restitution will be 1 and if the collision is perfectly inelastic

Motorcycle collisions are all too common in Bakersfield‚ and throughout California. In fact‚ the state’s Office of Traffic Safety reports that there were more than 450 motorcycle fatalities in 2013 alone. During that same year‚ many more people were injured in crashes involving motorcycles. Such accidents frequently have devastating results for motorcyclists due to the size difference between their bikes and other vehicles‚ and their lack of any external protection. Some motorcycle wrecks are unavoidable

Fortran Exercise #2: Coefficient Of Restitution 1. DEFINITION In this lab‚ we shall be studying the coefficient of restitution of a superball. The coefficient of restitution‚ COR‚ is the ratio of the bounce-back velocity to the original velocity of an object undergoing impact (such as a ball impacting the ground after being dropped from an initial height). Using the principle of the conservation of energy‚ the COR can be used to relate the bounce-back height to the original height of a ball dropped

Very few motorists get behind the wheel of their vehicles thinking that they will be involved in a collision. However‚ auto accidents occur all too often on the streets of New York City‚ and throughout the state. In fact‚ according to a New York State Traffic Safety Data report‚ there were more than 304‚000 car crashes in 2013 alone. Since getting into a wreck is often a frightening experience for those involved‚ it may help people to know what to do after an accident before one happens. Notify

Distractions outside of the car are a leading cause to collisions in automobiles. Cell phone usage is ranked second in the top three causes of automobile accidents.The number one reason for collisions is getting lost in your own thoughts. Distracted drivers can cause injuries and in some cases‚ death. Distractions inside and outside of the car‚ cell phone usage‚ and getting lost in thoughts are the three leading causes of automobile accidents. Distractions inside of the car are a leading

Introduction In society today‚ there are numerous reasons or factors as to why there are single vehicle collisions on American roads. Alcohol or substance abuse‚ animals crossing the road‚ and falling asleep at the wheel are just a few examples. There is not a whole that can be done for animal collisions‚ as more often than not the animal jumps out at the last second. But for the single vehicle collisions that do pertain to the car going off the road‚ there are ways to prevent the run off or help the driver
