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 5 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from the 3 story. How long does she have to get out of the way? Round to the nearest tenth. (A story is 12 feet.)
\n" ); document.write( "--------------------
\n" ); document.write( "h(t) = s - 16t^2
\n" ); document.write( "------------------
\n" ); document.write( "5 = 36 -16t^2
\n" ); document.write( "-16t^2 = -31
\n" ); document.write( "t^2 = 31/16
\n" ); document.write( "t = (sqrt(31))/4
\n" ); document.write( "t = 1.39.. seconds
