**Physics Problem on Momentum and Collisions**

**Problem Statement:**

Two gliders are moving toward each other on a horizontal track. 

- **Glider A**: 
  - Mass: 500 g
  - Initial Velocity: 50 cm/s

- **Glider B**:
  - Mass: 200 g
  - Initial Velocity: -50 cm/s

After a head-on collision, the following scenarios are observed:

- Glider A moves with a velocity of 20 cm/s.
- Glider B moves with a velocity of 25 cm/s.

**Explanation:**

This problem involves the conservation of momentum in a collision between two gliders. Both gliders initially move toward each other with equal and opposite velocities. After the collision, the gliders continue with new velocities, indicating either an elastic or inelastic collision, based on energy conservation and momentum.

In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, only momentum is conserved, not kinetic energy. By using the given data, one may calculate and verify the type of collision by comparing initial and final kinetic energy along with verifying the conservation of momentum. 

**Steps to Solve:**

1. Calculate the initial total momentum before the collision.
2. Calculate the final total momentum after the collision.
3. Compare the initial and final momentum to confirm conservation.
4. Optionally, calculate initial and final kinetic energies to determine the type of collision.

This exercise helps in understanding fundamental principles of physics like momentum conservation and classification of collisions.
