A particle moves on a coordinate line with acceleration StartFraction d squared s Over dt squared EndFraction equals 60 StartRoot t EndRoot minus StartFraction 21 Over StartRoot t EndRoot EndFraction , subject to the conditions that StartFraction ds Over dt EndFraction equals 9 and sequals20 when t equals 1. Find the velocity v equals StartFraction ds Over dt EndFraction in terms of t and the position s in terms of t.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

d.) yes, because the volume of the cone is greater than the volume of the sphere
