Two ball bearings of mass m each moving in opposite directions with same speed v collide head on with each other. If the collision is perfectly elastic, what will be the outcome of the collision ?

Explanation

To solve the problem of two ball bearings colliding elastically, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Initial Conditions:**
- Let the mass of each ball bearing be \( m \).
- The initial speed of one ball bearing moving to the right is \( v \).
- The initial speed of the other ball bearing moving to the left is \( -v \).
