A person walks at a velocity v in a straight line forming an angle `theta` with the plane of a plane mirror. With what velocity `v_(rel)` the apporaches his image ?

A person walks at a velocity v in a straight line forming an angle alpha with the plane of a mirror. Determine the velocity v_("rel") which he approaches his image, assuming that the object and its image are symmetric relative to the plane of the mirror.
