If h(t) represents the height of an object above ground level at time t and h(t) is given by: h(t)=-16t^2+14t+1 find the height of the object when at the time when the speed is zero. h(t)= (this problem is related to the previous problem that i posted: http://openstudy.com/study#/updates/4f20823ce4b076dbc348cc35)

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?
anonymous
  • anonymous
the function i was given in the beginning?
anonymous

????
campbell_st
  • campbell_st
yes
anonymous
  • anonymous
ok
anonymous
  • anonymous
i got a mixed number
campbell_st
  • campbell_st
that would be correct since ou substituted a fraction
anonymous
  • anonymous
i dont think my website accepts mixed numbers so i converted but i got the wrong answer when i did that
anonymous
  • anonymous
11 15/16
anonymous
  • anonymous
so i tried 191/16 which is wrong and i tried 11.9 which is also wrong
campbell_st
  • campbell_st
the fraction is (7)/(16 or seven sixteenths
anonymous
  • anonymous
yes, i know. what's the final answer?
campbell_st
  • campbell_st
there are 2 answers....1 and a value between 4 and 4.1
anonymous
  • anonymous
ok the correct answer is 4 (according to my hw site) how did you get 4?
campbell_st
  • campbell_st
by correctly substituting.... and knowing some calculus... sorry but this has become painful good luck with your solution
anonymous
  • anonymous
you couldve just showed ur work in the beginning so i wouldnt have asked so many questions but whatever -_-
campbell_st
  • campbell_st
this is a basic calculus concept.... please try and learn it, good luck
