The answer is commonly 12,
which is simply we can have 6 state variables,
and in each of those the helicopter might have its own velocity.
So for each of these variables, we have the state variable itself
and its velocity, which makes a total of 12.
This is completely nontrivial and something you probably can't know.
We just have to learn, but when you think about it, you realize this is the most general case
of a vehicle that can move in 3D at every possible location,
every possible orientation at any velocity.
That's called the dynamic state of a free-flying object.
答えは一般的には12です
単純に状態変数が6つあり
それぞれに対して速さを持てるからです
それぞれの変数について
状態変数と速さがあります
よって合計で12になります
これはかなり重要なことで

これについて考えてみると三次元空間で
どんな場所にも存在しあらゆる方向と速さを持てる
最も一般的なケースだと気づきます
これは自由飛行する物体の
動的な状態と呼ばれています
