Question: What is the total mechanical energy in a simple harmonic oscillator?

Options:

1. E = 1/2 k A^2
2. E = 1/2 m v^2
3. E = k A
4. E = m g h

Correct Answer: E = 1/2 k A^2

Solution:

The total mechanical energy in a simple harmonic oscillator is given by E = 1/2 k A^2, where A is the amplitude and k is the spring constant.
