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.
Cheers,
Stan H.
