Suppose a vertical plane mirror and a object which is placed at a distance of 4 m from the mirror. If we start moving the mirror with a velocity of 2m/s and also start moving the object at 3m/s. Then how should i can find the velocity at which the image moves and also the direction of motion of the image?

what is the direction of motion of the mirror and object? are they moving towards each other.?

in general when the mirror is moving with velocity V towards stationary object, the image moves with velocity 2V towards it.

direction can be found out by a simple logic, if the object is moving towards the mirror then image also moves towards mirror and vise versa
