A particle is dropped from the top of a tower of height `80 m`. Find the time of jurney and the speed with which it strikes the ground.

Explanation

To solve the problem of a particle dropped from a height of 80 meters, we will follow these steps:

### Step 1: Identify the Given Data
- Height of the tower (s) = 80 m
- Initial velocity (u) = 0 m/s (since the particle is dropped)
- Acceleration due to gravity (g) = 10 m/s² (approximated)

### Step 2: Use the Kinematic Equation to Find Final Velocity (V)
