Question

Consider the following situation: Recall from class we looked at a block attached to a horizontal spring, spring constant k, on a frictionless surface. We derived the equation for simple harmonic motion using two methods, force and energy conservation. For this question I would like you to do those derivations again, explaining each step as you go. Tell me why you do each step, and what physical properties allow you to do certain steps. a) Derive the simple harmonic motion equation for a block attached to a horizontal spring, spring constant k, on a frictionless surface using forces. b) Derive the simple harmonic motion equation for a block attached to a horizontal spring, spring constant k, on a frictionless surface using energy conservation. c) Do parts and (b)l give the same Simple harmonic equations? What are the frequencies of these equations? d) How do these equations change if friction was taken into account? Do not actually calculate or derive anything, just give me a physical explanation of what happens.
