A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient os restitution is 2/3. Find the velocities of both ball after the collision.

Explanation

To solve the problem, we will use the principles of conservation of momentum and the coefficient of restitution.

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Mass of ball A, \( m_A = 2 \, \text{kg} \)
- Initial velocity of ball A, \( u_A = 5 \, \text{m/s} \)
- Mass of ball B, \( m_B = 3 \, \text{kg} \)
