Answer:
ANSWERS ARE 100 % correct
Explanation:
trust me
Newton's First Law states that an object would remain at rest or in uniform motion in a straight line unless an unbalanced force acts upon it. So the speed would be the one that remains constant.
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 )
That ratio is called"efficiency". It doesn't need to be a percent.
It can just as well be a fraction or a decimal number.
