Answer:
a) the acceleration of the particle is ( v² - v² ) / 2as
b) the integral W = m( ² - v² )
Explanation:
Given the data in the question;
force on particle F = ma
displacement s = x - x
work done on the particle W = Fs = mas
we know that; change in energy = work done { work energy theorem }
m( v² - v² ) = mas
( v² - v² ) = as
( v² - v² ) = 2as
a = ( v² - v² ) / 2as
Therefore, the acceleration of the particle is ( v² - v² ) / 2as
b) Evaluate the integral W =
W = m( ² - v² )
Therefore, the integral W = m( ² - v² )
This type of question is based on a standard and is not
really calculated. According to the TX Adult Drivers Ed Course, the correct
answer to this question will be:
“44 feet”
<span>The distance of 44 feet actually corresponds to
approximately 1.5 seconds average reaction time of drivers.</span>
Sound will travel fastest in air at <span>15°C.
The reason why this is true is because air travels faster when the air is warm or hot. When it is cold outside, sound will not be transmitted as fast as when it is warm, which is why that is the correct answer.</span>
