How much has to be invested at 5.1% interst compound continuously to have 17,000 after 14 years

I do not know exactly, but it seems to be correct                                                                             A = Pe^(r*t)  Compounding continously

17,000 = Пэ^(.051*14)

17,000/e^(.714) = P

$8324.59  = P    

829 feet per second is your answer. You do this by doing 9,944in/s x ft./12in. Cancel out the in., and multiply to get 9,944ft in 12 seconds. Divide 9,944 by 12 to get around 828.6 ft., and then then round it up to get 829 ft. per second.
