so far this is all i have done for the code the Hero2 class has an image in another world of where the mouseClicked is being called 
    public void act() 
    {
        if (Greenfoot.mouseClicked(this))
        {
            Greenfoot.setWorld(new City());
            getWorld().removeObject(Hero2());
        }
    }

If you want to remove the Hero2 object from the new City world, you will need a reference to that world; and you will need a reference to the Hero2 object in that world: 
City city = new City();
Greenfoot.setWorld(city);
city.removeObjects(city.getObjects(Hero2.class));
By the way, your 'getWorld' method call on line 6 still returns the world where the click occurred. The line is equivalent to: 
this.getWorld().removeObject(< Hero2 object reference >);
where 'this' is the actor in the "then" active world that caused the act method to execute.

If you had the Hero2 object reference in an instance field and a method to return that Hero2 object in the City class: 
private Hero2 hero2 = new Hero2();

public Hero2 getHero()
{
    return hero2;
}
then you could remove it specifically with: 
City city = new City();
Greenfoot.setWorld(city);
city.removeObject(city.getHero());
