"Sit back in your chair honey, quit tryin' to climb out (wa'!)
I told you it's okay hai hai, want to ba-ba?
Take a night-night? nan-a-boo, goo-goo ga-ga?
Her make goo-goo ca-ca? da-da change your dia-dee.
Clean the baby up so her can take a nighty-nighty.
Your dad'll wake her up as soon as we get to the water.
Ninety-seven bonnie and clyde, me and my daughter."
Marshall 和 Hailie 一起去湖邊玩，兩個人一起往湖裡丟東西
東西在沉入水中時只受到三個力，重力、浮力和水的阻力
假設重力和浮力造成的向下加速度固定是 $\color{black}{A\ }$
水的阻力造成的向上加速度為 $\color{black}{kv^2}\ $ ( $\color{black}{v}\ $ 代表當前速度 )
那總體來說的向下加速度就是 $\color{black}{A - kv^2}\ $
請你求出在初速為 $\color{black}{0}\ $ 的狀況下，過了 $\color{black}{t}\ $ 單位時間，這個物體的位移、速度和加速度
(假設都沒碰到湖底)
輸入有多行
每行有正整數 $\color{black}{A, k, t}\ $
- $\color{black}{1≤ A,k ≤1000}\ $
- $\color{black}{1≤ t ≤ 10^7}\ $
輸出三行
第一行輸出 $\color{black}{x(t)=...}\ $
第二行輸出 $\color{black}{v(t)=...}\ $
第三行輸出 $\color{black}{a(t)=...}\ $
四捨五入到小數第 $\color{black}{2}\ $ 位
1 2 8 1 1 1 2 6 4
x(8)=5.31 v(8)=0.71 a(8)=0.00 x(1)=0.43 v(1)=0.76 a(1)=0.42 x(4)=2.19 v(4)=0.58 a(4)=0.00
