To solve the problem of how fast the image of a person moving towards a plane mirror approaches the person, we can follow these steps: ### Step 1: Understand the motion of the object and the image - The person is moving towards the plane mirror with a velocity \( v \). - According to the properties of plane mirrors, the image of the object (the person) will be formed behind the mirror at the same distance as the object is in front of the mirror. ### Step 2: Determine the velocity of the image relative to the mirror - Since the person is moving towards the mirror with a velocity \( v \), the image will also move towards the mirror with the same velocity \( v \) but in the opposite direction (towards the mirror). ...
