Question
![**Problem Statement:**
A compressed spring of \( k = 60 \, \text{N/m} \) is released from rest on a frictionless surface. What is the change in spring potential energy from its compressed position \( x = 0.40 \, \text{m} \) to its equilibrium position, in Joules?
**Instructions:**
Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

![**Title: Understanding Forces in Motion: An Elevator System**
**Description:**
A box of mass 4.0 kg hangs by a cable from the ceiling of an elevator. The elevator is moving up at a steady speed of 5.0 m/s for a distance of 8.0 m. Use g = 10 m/s². Consider the system consisting of the box and the Earth. Which of the following is considered the external force? Select all that apply.
**Diagram Explanation:**
The diagram shows an elevator represented as a vertical structure. Inside the elevator, a box labeled "m" is suspended by a cable from the ceiling. An upward arrow labeled "v" indicates the direction and motion of the elevator as it moves upward with a constant velocity.
**Options:**
- [ ] Tension force on the box
- [ ] Gravitational force on the box
**Note:** Select which option(s) correctly represent the external forces acting on the system containing the box and the Earth.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb0d3b0f0-c3f1-495e-ada9-018c1da2fe27%2F6cfb5ef0-9e88-45b1-af7d-180404507ef2%2Ftdyd9cb_processed.png&w=3840&q=75)
