A stone is projected horizontally from the top of a towar. At the same time , another stone is dropped down from the same height . Which ball will reach the ground earlier? Will they hit the ground with same velocity ?

Explanation

To solve the problem, we need to analyze the motion of both stones separately.

### Step-by-Step Solution:

1. **Understanding the Motion**:
- The first stone is projected horizontally from the top of the tower with an initial horizontal velocity (let's call it \( u \)).
- The second stone is dropped vertically from the same height with no initial velocity.
