Transcribed Image Text:**Recitation 8: Conservation of Energy**
1) A ball of mass \( m = 300 \, \text{g} \) is released from rest at a height \( h = 45 \, \text{cm} \) above a vertical spring of force constant \( k \) as shown in figure (a) to the right. The ball strikes the top of the spring and compresses it a distance \( d = 15 \, \text{cm} \) as shown in figure (b).
---
**Explanatory Note:**
This problem involves the principles of conservation of energy. Initially, the ball possesses gravitational potential energy due to its height above the spring. As the ball falls, this energy is converted into kinetic energy until it impacts the spring. Upon contact, the kinetic energy of the ball is transferred into the spring as potential energy, compressing it. The figures referred to in the text show the initial and compressed states of the spring but are not present in this transcription.

Transcribed Image Text:The image displays two diagrams illustrating a mass-spring system.
Diagram (a):
- A mass labeled "m" is positioned at a height "h" above a spring.
- The spring has a stiffness constant labeled "k".
- The mass is shown separated from the spring, indicating a point before contact.
Diagram (b):
- The mass "m" is now compressed into the spring, producing a compression distance labeled "d".
- The spring constant remains "k".
- This diagram represents the state after the mass has landed and compressed the spring.
These diagrams are used to study the concepts of potential energy, kinetic energy, and elastic potential energy in physics, particularly in analyzing vertical mass-spring systems. Diagram (a) represents the initial setup, while (b) depicts the compressed state after interaction.
