A ball of mass `m` is droppped from a height `h` on a platform fixed at the top of a vertical spring. The platform is depressed by a distance `x`. What is the spring constant `K`?

Explanation

To find the spring constant \( K \) for the given scenario, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- A ball of mass \( m \) is dropped from a height \( h \) onto a platform that is fixed at the top of a vertical spring. The spring compresses by a distance \( x \) when the ball hits the platform.

2. **Energy Considerations**:
