The distance that an object will fall in t seconds varies directly with the square of t.
\n" ); document.write( " An object falls 7 feet in 1 second.
\n" ); document.write( ":
\n" ); document.write( "The equation; (d = distance)
\n" ); document.write( "7t^2 = d
\n" ); document.write( "How long to fall 112 ft?
\n" ); document.write( "7t^2 = 112
\n" ); document.write( "t^2 = $\"112%2F7\"$
\n" ); document.write( "t^2 = 16
\n" ); document.write( "t = $\"sqrt%2816%29\"$
\n" ); document.write( "t = 4 seconds \n" ); document.write( "

\n" );
