Question 108578: The height h (in feet) of an object that is dropped from the height of s feet is given by the formula h = s-16t^2, where t is the time the object has been falling. A 4 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from 6 story. How long does she have to get out of the way? Round to the nearest tenth. (A story is 12 feet.)
You can put this solution on YOUR website! The height h (in feet) of an object that is dropped from the height of s feet is given by the formula h = s-16t^2, where t is the time the object has been falling. A 4 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from 6 story. How long does she have to get out of the way? Round to the nearest tenth. (A story is 12 feet.)
--------------------
The object will hit the top of her head when it's height is 4 ft.
---------------------
EQUATION:
4 = 6*12-16t^2
4 = 72 -16t^2
16t^2 = 68
t^2 = 68/16
t = 2sqrt(17)/4 = sqrt(17)/2 seconds
t is approximately 2.06 seconds
