wouldnt you just plug in 14 for t to get -32(14)+14=-434 or am i way off
this is differential calculus.... differentiate the function.... let the derivative = 0. This is when speed is zero.... The solution will give you the time (t) when the speed is 0. Once you have a value for t substitute it into the original equation to get the height when speed = 0. looks like t will be 7/16... which then needs to be substituted...
actually there are 2 solutions to this the one above and when t = 0 the speed is 0 as well....
where do i substitute 7/16?
the function i was given in the beginning?
i got a mixed number
that would be correct since ou substituted a fraction
i dont think my website accepts mixed numbers so i converted but i got the wrong answer when i did that
so i tried 191/16 which is wrong and i tried 11.9 which is also wrong
the fraction is (7)/(16 or seven sixteenths
yes, i know. what's the final answer?
there are 2 answers....1 and a value between 4 and 4.1
ok the correct answer is 4 (according to my hw site) how did you get 4?
by correctly substituting.... and knowing some calculus... sorry but this has become painful good luck with your solution
you couldve just showed ur work in the beginning so i wouldnt have asked so many questions but whatever -_-
this is a basic calculus concept.... please try and learn it, good luck
