If the bridge is 1053 feet above Arkansas river about how long will it take before before the stone hits the water

Assuming air resistance is negligible and a constant gravitational field.

h(t)=1053-16t^2  So the stone will hit the water when h(t)=0 so

1053-16t^2=0

16t^2=1053

t^2=65.8125, since t>0

t≈8.1 seconds  (to nearest tenth of a second)
