(Bài giải thì mình làm ở trên cho bạn rồi nha)

\(m=200g\\ L=20cm\\ w=5\left(\dfrac{rad}{s}\right)\\ a_{max}=?\left(\dfrac{m}{s^2}\right)\)

Giải:

\(L=2A\\ \Leftrightarrow A=\dfrac{L}{2}=\dfrac{20}{2}=10\left(cm\right)=0,1\left(m\right)\)

\(a_{max}=w^2.A=5^2.0,1=2,5\) (m/s²)

Vậy gia tốc cực đại của vật là 2,5 m/s²

Tóm tắt

\(m=3kg\\ h=5m\\ A=?\left(J\right)\)
