A stone at rest is dropped from a height and falls freely under gravity. Calculate the distance covered by it in the first two seconds. (g = 9.8 m`s^(-2)`)

Explanation

To solve the problem of calculating the distance covered by a stone dropped from rest in the first two seconds, we can use the second equation of motion. Here’s the step-by-step solution:

### Step 1: Identify the known values
- Initial velocity (u) = 0 m/s (since the stone is at rest)
- Time (t) = 2 seconds
- Acceleration due to gravity (g) = 9.8 m/s²

### Step 2: Write the second equation of motion
