Question: Please I want to explain the example Example - Block-spring System The problem: - The mass is attached to a spring, the spring is compressed
Example - Block-spring System The problem: - The mass is attached to a spring, the spring is compressed and then the mass is released. - A constant friction force acts. Conceptualize: The block will be pushed by the spring and move off with some speed. Categorize: - Block and surface is the system - System is non-isolated - There is a non-conservative force (friction) acting. Analyze: - Kf=Kifkd+Ws - Kf=1/2mv2 Finalize - Think about the result - Compare it to the result without friction
