The correct Answer is:
To find the maximum velocity of a simple harmonic motion (SHM) with amplitude \( A \) and time period \( T \), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the relationship in SHM**: In simple harmonic motion, the maximum velocity (\( V_{max} \)) can be expressed in terms of the amplitude (\( A \)) and the angular frequency (\( \omega \)). 2. **Formula for maximum velocity**: The formula for maximum velocity in SHM is given by: \[ V_{max} = A \cdot \omega \] where: - \( V_{max} \) is the maximum velocity, - \( A \) is the amplitude, - \( \omega \) is the angular frequency. 3. **Calculate angular frequency**: The angular frequency (\( \omega \)) is related to the time period (\( T \)) by the formula: \[ \omega = \frac{2\pi}{T} \] 4. **Substitute \( \omega \) into the maximum velocity formula**: Now, substitute the expression for \( \omega \) into the maximum velocity equation: \[ V_{max} = A \cdot \left(\frac{2\pi}{T}\right) \] 5. **Final expression for maximum velocity**: Simplifying the equation gives us: \[ V_{max} = \frac{2\pi A}{T} \] Thus, the maximum velocity of the simple harmonic motion is: \[ V_{max} = \frac{2\pi A}{T} \] ### Conclusion: The maximum velocity in simple harmonic motion with amplitude \( A \) and time period \( T \) is \( \frac{2\pi A}{T} \). ---
