Question

d) A man is going away from a plane mirror with a velocity of 2 m/s.
With what velocity is he receding from his own image in the plane
mirror?
​

Answer 1

Answer:

4 m/s

Explanation:

When you stand before a mirror, distance of you from mirror is equal to distance between mirror to you.

Thus, if you will move towards the mirror with a velocity of 2 m/s , the mirror image will move towards to you with velocity of 2 m/s only.

Thus, your speed towards mirror + mirror image speed towards you is 4 m/s, 2+2 = 4 m/s.
