Where's Lech?

 
Mischek:

Where's Leha?

Yeah, he went straight to the mouth. Fi.

He's busy. He's cooking up another nine-point stunt.

 
MetaDriver:

Yeah, I'm gonna go straight to the defense. Fi.

He's busy. He's setting up another nine-point bunt.

For WHAT?!?!

Let him decide by 9, huh?

 
To be honest, as soon as someone (let's not point the finger ;) ) suggested replacing the ball with a spring, I got the suspicion that someone had already googled it.
So I googled it too :)

But I think replacing the ball with a spring is not correct as the compression of the ball will be non-linear in the vertical direction.
In short, I demand a full-scale experiment!!!
Who has a perfectly elastic ball?

Мяч свободно падает с высоты 3м на горизонтальную поверхность. При каждом отскоке модуль скорости мяча уменьшается в 2 раза. Определить путь, пройденный мячом с начала падения до остановки. На теннисный мяч с высоты 1м падает кирпич и подскакивает снова почти на 1м. Оцените, на какую высоту после удара подскочит мяч.

Ahh, we've been cheated. The problem is a ball, the answer is a spring.

Well, no one can be trusted, no one.
