A stone is dropped freely from the top of a tower and it reaches the ground in 4 s. Taking g = 10 m `s^(-2)`, calculate the height of the tower.

Explanation

To solve the problem of calculating the height of the tower from which a stone is dropped, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Information:**
- Time taken to reach the ground (t) = 4 seconds
- Acceleration due to gravity (g) = 10 m/s²
- Initial velocity (u) = 0 m/s (since the stone is dropped)
