[SOLVED] Forming Images with a Plane Mirror
(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.
Don't really know any or I would have the answer.
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.
