A stone is thrown upwards with velocity 25m/s. Another stone is simultaneously thrown downward from the same point with speed 10 m/s. When the first stone is at a height 10 m. what is the relative velocity of first stone w.r.t second ?

Explanation

To solve the problem, we need to find the relative velocity of the first stone (thrown upwards) with respect to the second stone (thrown downwards) when the first stone is at a height of 10 m.

### Step-by-Step Solution:

1. **Identify Initial Velocities**:
- The first stone (A) is thrown upwards with an initial velocity \( u_A = 25 \, \text{m/s} \).
- The second stone (B) is thrown downwards with an initial velocity \( u_B = 10 \, \text{m/s} \).
