document.write( "Its t-value is t =  =  = 3.\r\n" );
document.write( "\r\n" );
document.write( "So, the maximal height is achieved at t = 3 seconds.\r\n" );
document.write( "\r\n" );
document.write( "The value of the maximal height is  =  = 144 ft.\r\n" );
document.write( "\r\n" );
document.write( "Answer. The maximal height is 144 ft at t = 3 seconds.\r\n" );
