57.If an object moves towards a plane mirror with a speed V, the image of the object will move towards the mirror with the speed 2V. explain why?

Q. What will be the image speed if:

Q. An object is moving with velocity v towards a stationary plane mirror. If mirror starts moving towards the object with speed v, the speed of the image of the object

Q. For a plane mirror, if an object moves with a velocity 'v' towards the mirror, then the image moves with a velocity 2v. How?

Q. If an object moves towards a plane mirror with speed '$v$' then:

Q. 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.
