**Physics Problem: Collision of Two Gliders**

A glider of mass \( m_1 = 5 \, \text{kg} \) has a velocity \( v_{1i} = +4 \, \text{ms}^{-1} \) before colliding with a second glider of mass \( m_2 = 15 \, \text{kg} \), initially at rest. After the collision, the two gliders couple together.

Determine the nature of this collision:

(a) Elastic  
(b) Partially inelastic  
(c) Totally inelastic  
(d) Impossible

**Explanation of Collision Types:**

- **Elastic Collision:** Both momentum and kinetic energy are conserved. The objects bounce off each other without any permanent deformation or heat generation.
  
- **Partially Inelastic Collision:** Momentum is conserved, but some kinetic energy is converted to other forms of energy (e.g., heat, sound). The objects may deform or generate heat but do not stick together.
  
- **Totally Inelastic Collision:** Momentum is conserved; however, kinetic energy is not. The objects stick together and move as a single unit post-collision.
  
- **Impossible Collision:** A scenario that cannot physically occur due to violation of the laws of physics.

**Note:** This problem involves understanding the principles of momentum and energy conservation in collisions.
