A particle of mass 40 g executes a simple harmonic motion of amplitude 2.0 cm. If the time period is 0.20 s, find the total mechanical energy of the system.

Explanation

To find the total mechanical energy of a particle executing simple harmonic motion, we can use the formula:

\[ E_{\text{total}} = \frac{1}{2} m \omega^2 A^2 \]

where:
- \( m \) is the mass of the particle,
