    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. Theory: 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: Perfectly inelastic. The items don 't move separated after the impact. 0 < e < 1: Inelastic. Kinetic energy disappears. e = 1: Perfectly elastic. Kinetic energy remains. e < 0: When velocity of share equal directions. e > 1: When energy is free. Mathematical Expressions: Coefficient of restitution: e = (Vb-Va)/(Ub-Ua) Object’s velocity after impact: e = V/U Design: The form of design is shown in the figure below. Explanation: 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) Investigative Question: Is momentum conserved during the collision of a brick and a trolley? Hypothesis: The momentum of the trolley before the collision will be equal to the…

    A recent article by Forbes magazine discusses the crash dilemma for self-driving cars. The specificities change from time to time but the crash dilemma stems from the idea of whether or not a self-driving car, when faced with no other option, crash into a specific person or its latter. An example of this would be if the car should crash into a group of elderly women crossing the street or into a kid who’s running across the street because he is late for school.
