even this speed, the Ke is equal

ft, the ball was hang on some

steel cable which must be hold

at some 'points' of the building.

As long as the pillars of building

is not damaged, the building will

not be crushed.

BTW, the ball is not solid. It is

assembled and empty inside. It

might even dissemble when hit the

ground. Most likely, it will not

bounce too much because the ground

is not that hard to bounce it.
