Question 178600: The formula d=16t^2 gives the approximate distance in feet (d) traveled by a falling object in t seconds. Approximately how long would it take a baseball dropped from the top of the Gareway Arch in St. Louis to hit the ground if the arch is 630 feet high?

The formula d=16t^2 gives the approximate distance in feet (d) traveled by a falling object in t seconds. Approximately how long would it take a baseball dropped from the top of the Gareway Arch in St. Louis to hit the ground if the arch is 630 feet high?
----------------------------
d = 16t^2
630 = 16t^2
t^2 = 630/16
Positive solution:
t = sqrt630)/4
t = 6.27 seconds
