[SOLVED] Forming Images with a Plane Mirror 1. The problem statement, all variables and given/known data (a) How rapidly does the distance between you and your mirror image decrease if you walk directly toward a mirror with a speed of 4.7 m/s? (b) Repeat part (a) for the case in which you walk toward a mirror but at an angle of 31° to its normal. 2. Relevant equations Don't really know any or I would have the answer. 3. The attempt at a solution I thought that for part (a) that the velocity would just be the same because if you're approaching a mirror at a certain speed wouldn't the distance between decrease at the same velocity? Is there a concept that I need to know to understand this? FYI: I have the Physics: Second Edition by James S. Walker. It's edited by Pearson Education and it has a red cover. If someone could just tell me what page to find something to help me with my answer that would be great. If I still don't understand I guess I'll put my questions here.
