Best ResponseYou've already chosen the best response.2s(t) = –G t^2 + V0(t) + H0 Vo = 42 ; H0 = 0; G = 16 s(t) = 16t^2 + 42t s'(t) = 32t + 42 = 0 at 42/32 = 21/16 = 1.3125

Best ResponseYou've already chosen the best response.1s'(t)=32t+42 s'(t)=0 when 32t+42=0 so t=42/32=21/16

Best ResponseYou've already chosen the best response.2s(t) = 16(1.3125^2) + 42(1.3125) = 27.5625 :) maybe

Best ResponseYou've already chosen the best response.0hello all. equation is \[42t16t^2\] max is when \[t=\frac{b}{2a}=\frac{21}{16}\] \[42\times \frac{21}{16} 16\times(\frac{21}{16})^2=\frac{441}{16}\]

Best ResponseYou've already chosen the best response.0btw you have to use \[h=h_0+v_0t16t^2\] because you are working in feet. and you don't need calc to find the vertex of a parabola, although you can

Best ResponseYou've already chosen the best response.0i spose but after getting \[\frac{b}{2a}\]for the 100th time maybe not.

Best ResponseYou've already chosen the best response.0on the other hand sometime it is silly to kill a fly with a grenade. you can get the vertex by simple algebra, completing the square or something.

Best ResponseYou've already chosen the best response.1omg i would love to kill a fly with a grenade how is that not fun

Best ResponseYou've already chosen the best response.0so not to be argumentative but i would not consider taking the derivative, setting to 0 and solving more or less mechanical than computing the vertex.
