A stone is dropped freely in a river from a bridge. It takes 5 s to touch the water surface in the river. Calculate :the distance covered by the stone in the first 2 s (g = 9.8 m`s^(-2)`).

Explanation

To solve the problem of calculating the distance covered by a stone dropped freely in a river from a bridge in the first 2 seconds, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information**:
- Time taken to cover the distance: \( t = 2 \) seconds
- Acceleration due to gravity: \( g = 9.8 \, \text{m/s}^2 \)
- Initial velocity of the stone when dropped: \( u = 0 \, \text{m/s} \) (since it is dropped from rest)
