**Introduction to Damped Mechanical Systems**

A damped mechanical system is shown in the figure below. The system has a spring constant (k) of \(2 \times 10^4 \, \text{N/m}\) and a mass (m) of 2 kg. It is subject to a sinusoidal driving force with a drive frequency of 10 Hz. The amplitude of the transient motion decreases 100 times after 10 drive periods. Your task is to answer the following questions:

1. What is the damping constant?
2. What is the frequency of the transient motion?
3. What is the amplitude of the driving force if the amplitude of the long-term oscillations is 0.1 m?

**Details Provided:**
- Spring constant, \(k = 2 \times 10^4 \, \text{N/m}\)
- Drive frequency, \(\text{drive freq} = 10 \, \text{Hz}\)

**Diagram of the System:**
