Question

average velocity between t=2 & t=4?
s(t) =t^3 -3t^2-9t+5

Answer 1

(s(4)-s(2) )/ 2 = -16m/s? this correct?

Answer 2

yes you do (s(4)-s(2))/(4-2) gj

Answer 3

why would i not input my numbers in a v(t) formula tho?

Answer 4

if the arithmetic is right, yes. it is
\[\frac{s(4)-s(2)}{4-2}\]

Answer 5

average velocity=slope of secant line
velocity=slope of a tangent line
two different things

Answer 6

average mean 'average'
\[\frac{distance traveled}{time elapsed}\]
