A neutron which is going to collde head on to a stationary `H` atom has intial kinetic energy of `24.5 eV`. Discuss different possibilites of collsion.

Explanation

To analyze the collision of a neutron with a stationary hydrogen atom with an initial kinetic energy of 24.5 eV, we will consider different possibilities of collision.

### Step-by-Step Solution:

1. **Understanding the Collision Types**:
- The collision can be classified into three main types: perfectly elastic collision, inelastic collision (where energy is absorbed by the hydrogen atom), and perfectly inelastic collision.

2. **Perfectly Elastic Collision**:
