A particle travels along the x-axis such that its velocity is given by v(t) = (t^0.7 + 4t) cos (t^2). What is the average accele
Airida [17]

It's not clear to me what the given interval is supposed to be, so I'll use a generic one, [a, b] with a < b.

The average acceleration of the particle over this interval is given by the average rate of change of v(t),

a_{\rm ave} = \dfrac{v(b) - v(a)}{b - a} = \boxed{\dfrac{(b^{0.7}+4b)\cos(b^2) - (a^{0.7}+4a)\cos(a^2)}{b - a}}

How are the solution sets to s&lt;3 and |s|&lt;3 different ?
Contact [7]

Answer:

they are different because of the mode sign on the second 's',

which if you are wondering what it stands for,

it represents only the magnitude of the value needed, not its sign,

let the assumed value of s be -5,

for example iin the first case, s < 3

hence s = -5, and it is true for s < 3

OR

if we take the second case, lsl < 3

that would be s = 5 [ not -5], which would not be true for lsl < 3

i hope u understood it,

if any more questions...please ask :)
