Form the top of a tower `100 m` in height a ball is dropped and at the same time another ball is projected vertically upwards from the ground with a velcoity of `25 ms^(-1)`. Find when and where the two balls will meet.

Explanation

### Step-by-Step Solution

1. **Identify the given information:**
- Height of the tower, \( h = 100 \) meters.
- Initial velocity of the ball dropped from the top of the tower, \( u_1 = 0 \) m/s.
- Initial velocity of the ball projected upwards from the ground, \( u_2 = 25 \) m/s.
- Acceleration due to gravity, \( g = 9.8 \) m/s².
