Two balls A and B of masses m and 2 m are in motion with velocities 2v and v, respectively. Compare: Their inertia.

Explanation

To compare the inertia of two balls A and B with masses m and 2m, and velocities 2v and v respectively, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Masses of the Balls:**
- Let the mass of ball A be \( m \).
- Let the mass of ball B be \( 2m \).
