Spring is pulled down by 2 cm. What is amplitude of its motion?

Options

A. 0 cm
B. 6 cm
C. 2 cm
D. 4 cm

Answer

To solve the problem of determining the amplitude of motion when a spring is pulled down by 2 cm, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
A spring is pulled down by 2 cm from its equilibrium position. We need to find the amplitude of its motion.

2. **Definition of Amplitude**:
The amplitude of a spring's motion is defined as the maximum displacement from its equilibrium position.

3. **Identify the Displacement**:
In this case, the spring is pulled down by 2 cm. This displacement from the equilibrium position is what we need to consider.

4. **Amplitude Calculation**:
Since the spring is pulled down by 2 cm, this value directly represents the maximum displacement from the equilibrium position. Therefore, the amplitude \( A \) of the spring's motion is equal to the displacement:
\[ A = 2 \, \text{cm} \]

5. **Conclusion**:
The amplitude of the spring's motion when it is pulled down by 2 cm is 2 cm.

### Final Answer:
The amplitude of the spring's motion is **2 cm**.
