Images that stir excitement in a very comprehensive proponents of Newtonian physics. The sultry star could it really, as it says in the lyrics of his song, joining her lover to destroy the walls "like a wrecking ball"?

How fast the wrecking ball she hits the wall?

First calculate the potential energy ( E p )  of the ball - ie its energy before it starts to move.

E p = mgh , where m is the mass of the ball (estimated at 1 ton), g the acceleration due to gravity and h is the height from the position of equilibrium.
