*maximum height

OpenStudy (anonymous):

round to the nearest whole foot

OpenStudy (anonymous):

\(V_0=120 \) \(h_0=2\) substitute this into: \(h(t)=-16t^2+V_ot+h_o \) Lter find a vertex of this parĂ¡bola. This will be your max hight

OpenStudy (anonymous):

so -b/2a?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

3.75?

OpenStudy (anonymous):

and rounding to the neares foot is 4ft?

OpenStudy (anonymous):

now put this value instead of t into the equation and find h(t)

OpenStudy (anonymous):

227ft why did i need to find that?

OpenStudy (anonymous):

because what you found first is t at which ball obtains it's max height, but, ofcourse, it's not the height it self, :)

OpenStudy (anonymous):

so my answer is within the range of 3.74-3.76?

OpenStudy (anonymous):

your answer = \(-16(3.75)^2+120(3.75)+2\)

OpenStudy (anonymous):

so my real answer is 227ft?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

yes i got it! thank you!

OpenStudy (anonymous):

yw

OpenStudy (anonymous):

give the guy a medal. geez.
