        var Utils = new Class({});
        Utils.extend({
            //static properties
            MAX_SPEED:100,
            //static functions
            sum:function(a,b){return a+b;},
            multiply:function(a,b){return a*b;}
        });
        document.write(Utils.sum(5,2)*Utils.MAX_SPEED);
