It takes about of a second to dissipate the kinetic energy from an impact throughout the vehicle.

It takes about 7/10 OF A SECOND to dissipate the kinetic energy from an impact throughout the vehicle.

Explanation:

Kinetic energy is referred to as the energy possess by a moving object. A moving vehicle possesses kinetic energy. When a moving vehicle collides with another vehicle or some other objects, the collision generate an impact with higher amount of kinetic energy, which must be dissipated.

The amount of time that it takes to dissipate the impact energy generated by a collision depend on the speed at which the vehicle was travelling before the event and the type of object that the vehicle collide with. Generally, it takes about 7/10 of a second to dissipate the kinetic energy from an impact throughout the vehicle.  

elizabeth loftus conducted a study to observe the reliability of eyewitnesses during the 1970s. their baseline was to define how accurate are the recollections of eyewitnesses.

her studies do not support the use of eyewitness. loftus mentions in her work that we are not required to recall some experiences, meaning that rarely an individual eyewitness testimony is trustworthy. a good example is presented in her work, where all individuals watched a video and were than asked "about how fast were the cars going when they hit/smash? ". the testimonies changed based on the word she used to make the question (hit or smash), proving the fragility.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
