(a story is 12 feet)..help!!!!!!!!!!!!!!! \n" ); document.write( "

Starting with the given formula:
\n" ); document.write( " $\"h+=+s-16t%5E2\"$ Substitute h = 5 ft. and s = 3(12ft.) = 36 ft.
\n" ); document.write( " $\"5+=+36-16t%5E2\"$ Subtract 36 from both sides.
\n" ); document.write( " $\"-31+=+-16t%5E2\"$ Divide both sides by -16.
\n" ); document.write( " $\"-31%2F%28-16%29+=+t%5E2\"$ Take the square root of both sides.
\n" ); document.write( " $\"t+=+5.57%2F4\"$
\n" ); document.write( " $\"t+=+1.4\"$ seconds.
\n" ); document.write( "The woman has 1.4 seconds to get out of the way of the falling bottle, but, if I were she, I would waste no time in doing this algebra! I would move immediately! \n" ); document.write( "
