Question 728325
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 stuntman jumps from a rooftop 325 ft off the ground. How long will it take him, falling freely, to reach the ground? 
---------------
325 = 16t^2
Solve for t
Ignore the negative solution.
