As an object moves towards a convex mirror, the image

A linear object AB is placed along the axis of a concave mirror. This object is moving towards the mirror with speed U. The speed of the image of the point A is 4U and the speed of the image of B is alSO 4U btu in opposite direction. If the center of the line AB is at a distance L from the mirror then find out the length of the object.

If an object moves towards a plane mirror with a speed v at an angle theta to the perpendicular to the plane of the mirror, find the relative velocity between the object and the image.

Assertion : When object moves in a direction perpendicular to a fixed plane mirror then velocity of image with respect object is double in magnitude to the magnitude of velocity of object. Reason : Distance of image from the plane mirror is always same as distance of object from the plane mirror.
