Question 210106: The formula s = 16t2 is used to approximate the distance s, in feet, that an object falls freely (from rest) in t seconds. Use this formula to solve the problem. (Round answer to the nearest tenth.)
A branch of a tree hangs 575 ft above the soil. If a twig breaks off, how long will it take it, falling freely, to reach the soil?

In this problem, s = 575 ft.
s+=+16t%5E2 Substitue s = 575
575+=+16t%5E2 Divide both sides by 16.
35.9375+=+t%5E2 Take the square root of both sides.
5.99+=+t
The twig hits the ground in 6 seconds.
