blueberries change its properties after some time. So, the device will use their properties as its working methodology. Then it will select fresh blueberries on the basis of their properties.
As blueberries age or become bruised, they tend to soften. Therefore, their coefficient of restitution decreases. First we need to understand what is coefficient of restitution.
Coefficient of Restitution:
COR is the extent of restitution of an impact between two objects. Also, for the kinetic energy how long it remains for the objects to bounce from each other.
COR = e = (Relative velocity after collision)/(Relative velocity before collision)
Range of Coefficient of Restitution:
For COR range, it’s between 0 and 1.0.
e = 0:
The items don 't move separated after the impact.
0 < e < 1:
Kinetic energy disappears.
e = 1:
Kinetic energy remains.
e < 0:
When velocity of share equal directions.
e > 1:
When energy is free.
Coefficient of restitution:
e = (Vb-Va)/(Ub-Ua)
Object’s velocity after impact:
e = V/U
The form of design is shown in the figure below.
Here, blueberries are dropped from a height of 5 ft on an inclined plane. If the blueberry is fresh one, it will bounce back with huge force and will go above the hurdle of height “h” direct into a collecting bucket. If the blueberry is bruised or aged,…
if one object loses momentum the other object must gain an equal amount of momentum.
An isolated system is one which the only forces are between the bodies that are colliding or exploding, no outside forces must be acting. (M.Mann, 2013)
Is momentum conserved during the collision of a brick and a trolley?
The momentum of the trolley before the collision will be equal to the…
message is more important than devoting their complete attention to maneuvering around the road. In addition, unsafe driving behaviors such as speeding, cutting off another driver, or driving under the influence are all link to an individual’s personal ambition to get from starting and ending destination quicker. Unsafe drivers choose to priorities their personal endeavor over other’s safety.

An Accident Waiting to Happen
In life, an innocent bystander, parent, or friend may receive news that changes their life forever. A death of a loved one is something that can drop anyone to their knees in agony. Karl Shapiro’s “Auto Wreck” faces the hard truth that is involved in a car accident. In summary, “Auto Wreck” is a gut-wrenching retelling of a brutal mishap in which two cars collide in a fatal accident. The poem concludes on a more philosophical note explaining the certainty that is…
What texting and driving has done and caused with teenagers and adults in america today? Texting, looking, dialing, and talking on your phone while driving has caused over million auto crashes nationwide. Most of those crashes are caused by young teens between the ages of 16 - 19. The cause of why adults and young teens getting and causing car crashes and why those distractions can injure or end someone 's life. The stactices of auto crashes in the U.S , death and injury rate of people caused by…
Have you ever being on a long car ride and wish the car can drive itself? Well the technology is closer then you thing. Many car company are working on this technology come true. With this kind of technology come many consider. You may be asking you self what consider what the big deal? While with technology comes many new things that people might have never thought about from social, cultural, political, economic, and environment effect of this technology coming true.
What is the social impacts…
motorcyclists are more likely to be killed or severely injured in crashes during racing or off road riding. You’ll lose 1mm of flesh for every 1mph you're going over 30mph when you hit road. Hence riders wear armour to protect against injury from falling off, hitting other riders and bikes, debris kicked up from the rear wheel of leading bikes, and from running into track barriers protecting the public. This armour protects the extremities from breakage and dislocation and the back and chest…
and driving, the person behind the wheel probably will not notice that they are about to crash until it happens and it 's too late to prevent the accident. The driver then feels guilty for what has happened and the family is left to grieve over the loss of their loved one. It it said that both teens and adults are guilty of texting and driving but almost half of those that admit it will not stop. The minimum amount of time it takes to crash a car without looking is approximately 5…
safer. The question that comes to mind when seeing these statistics on car accident fatalities is how many of them could have been prevented? And if possible, what methods would be used to do so? Well, the purpose of this paper is to indicate the changes that would be made and how to try to change them. This will be accomplished through three points: one, making a mandatory driving class, this would raise awareness. Two, every Ga resident, regardless of age, must renew their license every year,…
Did you know that according to “Injury Prevention and Control” that more than 9 people are
killed in a car crash every single day and more than 1,153 people are injured in the U.S. because
of car crashes involved with distracted driving? What exactly is distractive driving? Distractive
driving is doing anything to take your eyes away from the road and not focusing on driving the
vehicle. Such as using a cell phone, texting, eating, using a GPS, etc. Car crashes are terrifying!
