A man standing on the edge of a cliff throws a stone straight up with initial speed (u) and then throws another stone straight down with same initial speed and from the same position. Find the relation of the speeds. The stones would have attained when they hit ground at the base of the cliff.

Explanation

To solve the problem, we will analyze the two scenarios separately: one for the stone thrown upwards and one for the stone thrown downwards. We will then find the final speeds of both stones when they hit the ground.

### Step 1: Analyze the stone thrown upwards

1. **Initial Conditions**:
- Initial speed (u) = u (upwards)
- Acceleration (a) = -g (downwards, where g is the acceleration due to gravity)
- Final position (s) = -h (where h is the height of the cliff)
