A particle of mass m moving with speed v in position x - direction collides perfectly inelastically with another identical particle moving with same speed in positive y - direction . Find final velocity of the combination.

Explanation

To solve the problem of finding the final velocity of two identical particles colliding perfectly inelastically, we can follow these steps:

### Step 1: Understand the Initial Conditions
We have two particles, each with mass \( m \):
- Particle 1 is moving in the positive x-direction with speed \( v \).
- Particle 2 is moving in the positive y-direction with speed \( v \).

### Step 2: Write the Initial Momentum
