 Question 34985: The distance d, in feet, a bomb falls in t seconds is given by How many seconds are required for a bomb released at 21,000 feet to reach its target? (If necessary, round your answer to two decimal places.) A) 1167.12 seconds B) 185.76 seconds C) 92.88 seconds D) 2972.19 seconds Answer by stanbon(57245)   (Show Source): You can put this solution on YOUR website!The distance d, in feet, a bomb falls in t seconds is given by How many seconds are required for a bomb released at 21,000 feet to reach its target? (If necessary, round your answer to two decimal places.) A) 1167.12 seconds B) 185.76 seconds C) 92.88 seconds D) 2972.19 seconds d=16t^2/(1 +.06t) 21000(1+0.06t)=16t^2 21000+1260t-16t^2=0 4t^2-315t-5250=0 Graphing this I find the zero at 92.88 seconds.
