A bullet of mass `20g` is fired horizontly with a velocity of `150ms^(-1)` from a pistol of maass `2kg`. What is the recoil velocity of the pistol?

Explanation

To find the recoil velocity of the pistol when a bullet is fired from it, we can use the principle of conservation of momentum. Here’s the step-by-step solution:

### Step 1: Identify the given data
- Mass of the bullet (m1) = 20 g = 20/1000 kg = 0.02 kg
- Mass of the pistol (m2) = 2 kg
- Velocity of the bullet (v1) = 150 m/s
- Recoil velocity of the pistol (v2) = ?
