A bomb of mass 12 kg explodes into two piece of masess 4 kg and 8kg . The velocity of mass 4 kg is 20 m/s . Find the velocity of mass 8 kg

Explanation

To solve the problem step by step, we will use the principle of conservation of momentum. Here’s how we can approach the question:

### Step 1: Understand the Problem
We have a bomb of mass 12 kg that explodes into two pieces: one piece has a mass of 4 kg and the other has a mass of 8 kg. The velocity of the 4 kg piece after the explosion is given as 20 m/s. We need to find the velocity of the 8 kg piece.

### Step 2: Apply the Conservation of Momentum
According to the law of conservation of momentum, the total momentum before the explosion must equal the total momentum after the explosion.
