Question 299009: Please help I got a few answers:
s=16t^2 is used to approximate the distance x, in feet, that an object falls freely ( from rest) in t seconds. Use this formula to solve the problem round to the nearest tenth
A man drops his keys off a building 1420 ft. high. How long does it take the keys, falling freely, to hit the ground?
Thank you

------------
Solve 16t^2 = 1420
t^2 = 88.75
t = 9.42 seconds
