: Reading problem
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 6 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from the 2 story. How long does she have to get out of the way? Round to the nearest tenth (A story is 12 feet).
I appreciate anyone who can help solve this problem. Thank you. This question is from textbook Intermediate Algebra
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 6 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from the 2 story. How long does she have to get out of the way? Round to the nearest tenth (A story is 12 feet).
;
From the above information we have to assume that total distance of the dropped bottle will be: 2(12) - 6 = 18 ft; therefore s=18'
:
18 - 16t^2 = 0
:
-16t^2 = -18
:
t^2 =
:
t^2 = 1.125 sec
t =
t = 1.06 or about 1 second to get of the way.
