Two indentical balls A and B moving with velocities `u_(A)` and `u_(B)` In the same direction collide. Coefficient of restitution is e.
(a) Deduce expression for velocities of the balls after the collision.
(b) If collision is perfectly elastic, what do you observe?

Explanation

To solve the problem, we will break it down into two parts as stated in the question.

### Part (a): Deduce expression for velocities of the balls after the collision.

1. **Identify the Initial Conditions**:
- Let the initial velocities of balls A and B be \( u_A \) and \( u_B \), respectively.
- Let the final velocities after the collision be \( v_A \) and \( v_B \).
