OpenStudy (alekos):

didnt you ask this yesterday?

OpenStudy (anonymous):

yeah

OpenStudy (alekos):

I thought so! the derivative of s(t) = s'(t) = -6

OpenStudy (alekos):

are you sure that you've given us the correct equation?

OpenStudy (anonymous):

yeah thats what my homework says

OpenStudy (alekos):

ok then the velocity = s'(t) = -6 at all times t

OpenStudy (anonymous):

so the answer is -6?

OpenStudy (alekos):

yep

OpenStudy (alekos):

is that what the back of the book says?
