A person moves with a velocity `v` towards a plane mirror. With what velocity does his image move towards him ?

When a person moves towards a mirror with velocity 3v, by which velocity his image moves relative to himself ?

STATEMENT -1 : when an object moves towards a plane mirror with a certain velocity, its image will also move with same velocity. and STATEMENT - 2 : The distance from mirror to image is equal to distance of object from mirror.

As an object moves towards a convex mirror, the image

Thre identical masses are kept at the corners of an equilateral triangle ABC. A moves towards B with a velocity V, B moves towards C with velocity V, and C moves towards A with same velocity V. Then the velocity of centre of mass of the system of particles is
