The bob of a pendulum is moving with a speed of 5 m/s while passing through mean position . Calculate its speed at the position when it makes an angle of `30^(@)` with the vertical . The length of pendulum is 0.6 m / Use ` g = 10 m//s^(2)`

Explanation

To solve the problem, we will use the principle of conservation of mechanical energy. The total mechanical energy (kinetic + potential) at the mean position will be equal to the total mechanical energy at the position where the pendulum makes an angle of 30 degrees with the vertical.

### Step-by-Step Solution:

1. **Identify the initial conditions:**
- Speed at the mean position (v_initial) = 5 m/s
- Length of the pendulum (L) = 0.6 m
- Angle with vertical (θ) = 30 degrees
