The bob of a simple pendulum executes simple harmonic motion with amplitude 4 cm and frequency 10 vibrations per second. Calculate the kinetic energy of the bob in lowest position if mass of bob is 2 kg.

Explanation

To solve the problem, we need to calculate the kinetic energy of the bob of a simple pendulum at its lowest position. We will use the following steps:

### Step 1: Identify the given values
- Amplitude (A) = 4 cm = 0.04 m (convert to meters)
- Frequency (f) = 10 vibrations per second
- Mass (m) = 2 kg

### Step 2: Calculate angular frequency (ω)
