if you drop an object from 1936 feet, how long until it hits the ground?
\n" ); document.write( "Let t = time in seconds
\n" ); document.write( ":
\n" ); document.write( "-16t^2 + 1936 = 0
\n" ); document.write( ":
\n" ); document.write( "-16t^2 = -1936
\n" ); document.write( "Divide both sides by -16
\n" ); document.write( "t^2 = 121
\n" ); document.write( "t = \"sqrt%28121%29\"
\n" ); document.write( "t = 11 sec
\n" ); document.write( "
\n" );
