Two ice skaters A and B approach each other at right angles. A has mass 30 kg and velocity 1 mis and B has a mass of 20 kg and velocity 2 m/s. They meet and stick together. The final velocity of couple is :

Explanation

To solve the problem of finding the final velocity of the two ice skaters A and B after they collide and stick together, we will use the principle of conservation of linear momentum. Here’s a step-by-step solution:

### Step 1: Understand the Problem
We have two skaters A and B approaching each other at right angles. Skater A has a mass of 30 kg and a velocity of 1 m/s, while skater B has a mass of 20 kg and a velocity of 2 m/s. After they collide, they stick together.

### Step 2: Define the Variables
- Mass of skater A, \( m_A = 30 \, \text{kg} \)
- Velocity of skater A, \( v_A = 1 \, \text{m/s} \)
