A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) =  16t2 + 576t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit.
i don't even understand what she is wanting me to do??????????

Best ResponseYou've already chosen the best response.216t (t+36) is as far as you can go now the key here is to remember your zero times tables ....

Best ResponseYou've already chosen the best response.216t (t+36) = 0 when 16t=0, or when t+36 = 0 what values do we get for "t"?

Best ResponseYou've already chosen the best response.0if 16t=0 then t is 0 and if t+36=0 then t=36

Best ResponseYou've already chosen the best response.2good, so lets say it takes from t= 0 to 36 seconds to go up and come back down to the ground. (h=0) the great thing about a parabola is that it takes the same amount of time to go up as it does to go down. the highest point is therefore, half of the time interval. what is half way between 0 and 36 ?

Best ResponseYou've already chosen the best response.2good, then it takes 18 seconds for it to reach its maximum position, and another 18 seconds to fall back down to the ground

Best ResponseYou've already chosen the best response.0h(t)=16t^2+576t \[\frac{ dh }{ dt }=32t+576\] when it is at maximum height dh/dt =0 32t+576=0,t=576/32=18 sec. when t=18 sec., h=16*18*18+576=18(16*18+32)=18*32(9+1)=576*8=4608 maximum height reached=4608 units.
