Pada simpangan berapakah gerak harmonik ernergi potensial nya 3 kali energi kinetik nya

Diketahui :
Ep = 3 Ek ===> Ek = 1/3 Ep

Tanya :
Simpangan, Y = ___?

Jawab :
Em = Ep + Ek
1/2.k.A^2 = Ep + 1/3.Ep

1/2.k.A^2 = 4/3.Ep

1/2.k.A^2 = 4/3. (1/2.k.Y^2)

A^2 = 4/3. Y^2

Y^2 = 3/4. A^2

Y = akar (3/4. A^2)

Y = 1/2. A. Akar (3) satuan panjang
