Question 331224: A ball is dropped from a height of 150ft how long will it take for it to reach the ground? all i know is that im suppose to figure it out in a quadratic equation form and that objects fall at a rate 32.2ft per second per second(32.2ft squared) Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! A ball is dropped from a height of 150ft how long will it take for it to reach the ground?
objects fall at a rate 32.2ft per second per second (32.2ft squared)
:
The average rate of fall from a dropped object: *32.2 = 16.1 ft/sec
:
h = -16.1t^2 + 150
where
h = height of a dropped object after t seconds
h=0 when it hits the ground
-16.1t^2 + 150 = 0
-16.1t^2 = -150
Divide both sides by -16.1
t^2 = +9.31677
t =
t = 3.05 sec
