Solution

The correct option is A $5 m s^{- 1}$
In case of a plane mirror, object distance is equal to image distance.
We know that, $speed = \frac{distance}{time}$ . Therefore, if the person moves with a constant speed of $5 m s^{- 1}$ , his image would also move with the same speed.

A person moves away from a mirror at a constant speed of 5 ms−1. At what speed would his image move with respect to the mirror?

The correct option is A 5 ms−1In case of a plane mirror, object distance is equal to image distance. We know that, speed=distancetime. Therefore, if the person moves with a constant speed of 5 ms−1, his image would also move with the same speed.
