Complete question: A particle is moving along x-axis with 4 m/s in front of plane mirror which is moving along negative direction with 2 m/s. Speed of image with respect to ground will be...?

(a) 6 m/s (b) 4 m/s

(c) 8 m/s (c) 2 m/s

Answer: 4 m/s

Explanation:

Total distance between object and image = 2x

Mirror moving towards object = v

Image moving towards object = 2v

v = 2 m/s

Image will move towards the object with speed = 2x2 = 4 m/s
