Explanation:

11.2 km/s

-So mathematically it is less than 11.2 for moon to escape from earth but practically a body will need minimum 11.2km/s to go away forever from earth and get affected to sun's gravitational field. It will be less than the value of 11.2 km/s. This value of escape velocity is for any object which is at Earth's surface.
