Question

a horse rider is moving towards a big mirror with velocity v. the velocity of his image with respect to him is -?

Answer 1

We add a velocity opposite to the direction of horse velocity to horse and to mirror, to make the horse at rest.

Then the velocity of his image with respect to him will be 2v

Answer 2

Answer:

2v

Step-by-step explanation:

as we know image of any thing made by plane mirror is of same height. and when thing is coming toward mirror with velocity v , image will move toward thing with velocity of 2v . image of plane mirror is always follow all the law of light. so if thing is rotating with angle α then its image will rotate by 2α.

so horse rider image will move with velocity of 2v towards him.
